Terraplus KT-20 Magnetic Susceptibility Meter Console

THIS LISTING IS FOR THE TERRAPLUS KT-20 CONSOLE ONLY. A SENSOR IS REQUIRED TO OPERATE THIS UNIT.

The KT-20 is a handheld console with different modules for measuring a sample's magnetic susceptibility, conductivity, changeability and resistivity, and density. Its modular design allows the KT-20 to be available in many configurations of measurement capabilities, and new modules or upgrades can be added at any time.

The KT-20 is available with a range of sensors with different shapes and frequencies. Users can interchange the sensors on the console, allowing the KT-20 to be adapted to different sizes and types of samples or used in various applications.

The KT-20 console includes several built-in features to increase the amount of information that can be added to a measurement record. These features include a GPS receiver to obtain the measurement's coordinates, a digital camera to photograph the sample, a microphone to record voice notes, and a virtual keyboard to enter text notes.

Benefits

  • Three modes of operation: single measurement, continuous scanner, and borehole to correlate measurement results to their depth in the borehole.
  • Multiple sensor frequencies and shapes to measure magnetic susceptibility and conductivity. Sensors are interchangeable to adapt the KT-20 to different samples or applications.
  • Curved sensors are dedicated to core logging.
  • The IP/Resistivity Module enables the KT-20 to measure the changeability and resistivity of geological samples. The module comes with either a Small or large sample holder to facilitate measurements of various sample sizes.
  • 3F-32 Large Diameter Sensor for soil investigations, mapping, and detecting shallow anomalies.
  • The KT-20's large LCD screen displays data in real-time. Stored records can also be reviewed directly on the console.
  • Split and full core corrections for standard drill rod diameters (AQ, BQ, HQ, NQ and PQ) and non-standard sizes (2.4 cm to 12 cm) for circular and rectangular sensors.
  • KT-20 console features built-in GPS receiver, digital camera, microphone and virtual keyboard for users to include additional information with measurement results.

Applications

  • A modular design and interchangeable sensors give the KT-20 the flexibility to measure a wide variety of types and sizes of samples, or adapt the console for different applications.
  • Drill Core: Curved sensors for measuring cylindrical core. Their unique shape permits the entire surface area of the sensor to make contact with the core sample, improving both the sensitivity and repeatability of the measurements. Use the IP/Resistivity Module to measure the sample‚ chargeability and resistivity.
  • Prospecting: Use the KT-20 in the field for prospecting. Circular sensors are utilized for measuring large samples, like outcrops. The 10 kHz single-frequency circular sensor features a pin mode that aids in measuring samples with uneven, rough surfaces.
  • Powders and Chips Samples: Use any circular or rectangular sensor to collect measurements on powders, rock chips and other loose samples. These types of samples should be formed into a bulk mass, with a surface area larger than the sensor, and at least 2-inches thick.
  • Environmental Investigations: The 3F-32 large diameter sensor has a greater depth penetration than the single- and dual-frequency sensors. Use the 3F-32 to map soils, or in agricultural applications.
  • Archaeology: The 3F-32 large diameter sensor is able to map the magnetic susceptibility and conductivity of soils, or detect shallow targets. Smaller sensors can be used to collect additional information on artifacts.

GeoView 2 Software

GeoView 2 is an easy to use data management and visualization software program that is compatible with all Windows operating systems.

It enables users to download, store and view a KT-20's data on a PC and export it to Excel. Data is organized by date, or by instrument serial number when there is data from multiple instruments. Additional information collected can be viewed in GeoView 2, including averaged readings, standard deviation, text and voice notes, pictures and GPS coordinates.

GeoView 2 is also a data visualization tool. Numerical values from discrete measurements are displayed in a table format; data from scanned and borehole mode measurements are displayed as a graph. Data from the borehole mode will show measurements from specific depths.

Measurement Modules

The KT-20 has four modules to measure magnetic susceptibility, conductivity, induced polarization (IP)/resistivity, and density. Magnetic susceptibility and conductivity can be measured simultaneously with circular or rectangular sensors, when both modules are activated. The KT-20 is available in any configuration, and all modules can be added to the console at a later date. Most upgrades can be completed through the internet, although a new sensor may be required. Sensitivities of the magnetic susceptibility and conductivity modules are dependent on sensor frequency and shape.

Magnetic Susceptibility

Measurement Range from 1 x 10-7 to 10 SI Units with Plus upgrade for iron ore applications (see options section for details)

Applicable sensors include 1/10 kHz dual-frequency sensors, 10 kHz circular sensor, 10 kHz curved sensors, and 3F-32 large diameter sensor. Sensitivity is dependent on sensor frequency and shape (see sensor section for details).

Conductivity

Measurement Range: Dependent on sensor frequency and shape (see sensor section for details)

Cx upgrade to increase conductivity measuring range (see options section for details)

Applicable sensors include 10/100 kHz dual-frequency sensors, 10 kHz circular sensor, 100 kHz curved sensors, and 3F-32 large diameter sensor. Sensitivity is dependent on sensor frequency and shape (see sensor section for details).

Induced Polarization / Resistivity

Calculates chargeability using 20 standard windows, with arithmetic, logarithmic, semi- logarithmic and Cole-Cole plotting options.

Mx Fit calculation: an algorithm that calculates chargeability over several thousand data points increasing accuracy.

Resistivity and resistance measured.

Automatic voltage and current calibration.

Total Tau.

Pro upgrade to record full waveform analysis, raw data and more (see options section for details).

Operators can choose between two sample holder sizes, Small or Large, dependent on the length and width of the samples being measured.

Density

Enables the KT-20 to measure the density of a sample through water displacement. Includes a tensiometer, sample holder and water containment bag.

Sensors

The KT-20 has a range of interchangeable sensors with different shapes and frequencies. Each shape and frequency has its own benefit or application. Users can swap sensors on the KT-20 to adapt the console to different sizes and types of samples, or for different applications.

Sensor Shapes:

  • Circular Sensors: Ideal for measuring large, flat samples. 10 kHz single-frequency sensor features a pin mode to measure samples with uneven surfaces.
    Dimensions: 66 mm diameter.
  • Rectangular Sensors: Used for measuring small, flat samples or split core. Dimensions: 65 mm x 38 mm
  • Curved Sensors: Designed to measure drill core samples. Their curved shape allows users to achieve a higher sensitivity for magnetic susceptibility or conductivity, while producing consistent, repeatable measurements. Dedicated curved sensors for BQ, HQ, NQ and PQ sizes.

Individual Frequencies:

  • 1 kHz: For measuring magnetic susceptibility on conductive samples. This frequency reduces the impact of conductivity on magnetic susceptibility measurements. This frequency is not suitable for measuring conductivity.
  • 10 kHz: Ideal frequency for measuring both magnetic susceptibility and conductivity simultaneously. Single-frequency 10 kHz sensors offer highest sensitivity for measuring susceptibility.
  • 100 kHz: Provides the highest sensitivity for conductivity measurements in low ranges. This frequency is not suitable for measuring magnetic susceptibility.

THIS LISTING IS FOR THE TERRAPLUS KT-20 CONSOLE ONLY. A SENSOR IS REQUIRED TO OPERATE THIS UNIT. SENSORS ARE SOLD SEPARATELY.

Works great (quick test)
Just got this and tested and works great I attached to my MacBook with Ethernet and had a solid connection I tested my steam deck by plugging in Ethernet then adding HDMI then adding power and everything worked as it was plugged in I tested my Nintendo switch even though it clearly states it's not supported and it did not work at all. Even the power pass through did nothing. This is not even remotely a problem since it was advertised as such but I figured it was with a try and worth noting

Despite some caveats; this is a versatile hub
The Anker 555 8-in-1 USB-C Hub is a good buy if you’re looking for a hub from a reputable brand. I use it with an M1 Macbook Air, and it has been reliable so far. This hub has the following ports: 1 USB-C data port, 1 USB-C Power Delivery Port, 2 USB-A data ports, 1 HDMI port, an Ethernet port, and a microSD/SD card reader. Charging, PD (Power Delivery): To keep my Macbook charging, I connect a PD (Power Delivery) capable cable to the USB-C port meant for PD. (The other USB-C Port on this hub is meant only for data.) Once connected, the hub will eventually become warm to the touch, but this hasn’t caused any problems so far. Video Performance - no problems in 1440p I can connect my 1440p 144hz monitor to this hub’s HDMI port and my Macbook Air has no problem outputting a refresh speed of 144hz, as well the lower refresh rates of 120hz and 60hz. (I do not have a 4k monitor, so I could not test that.) USB-A Ports - works flawlessly I’ve tried keyboards, USB Drives, and even gaming Mice. All of these devices work as expected when connected to the USB-A Ports. Ethernet - Excellent speed I've connect this hub using an Ethernet cable to Gigabit speed Internet. The speed is just as fast as other computers on the network, and there is no slowdown at all, even with most of the ports on the hub being used. Gaming Keyboards with USB-C connectors - some issues. Some peripherals such as keyboards with USB-C connectors may not work on the USB-C ports on this hub. I tried using a Glorious GMMK Mechanical Keyboard and it did not work with this hub’s USB-C ports. (Of course you could try to simply use a USB-C to USB-A adaptor and then connect via the other USB ports on the hub instead.) Extension Cable - Use a Thunderbolt 4 cable Although this is totally optional, I like to use a small, 6-inch USB-C Extension cable to allow this hub to have more slack away from my laptop when connected. To allow this to work, I had to use a Thunderbolt 4 extension cable. I've tried other cables such as a Thunderbolt 3 extension cable. However, some of the attached devices on the hub were not recognized. Only the the Thunderbolt 4 extension cable allowed all my attached devices to be recognized. Other devices I have successfully connected an external SSD via the USB-C data port on this hub. I also regularly use an external DAC using the USB-A ports connecting to an IFI HIP DAC. Both of these devices work perfectly with this hub. Data transfer speed is rated at 10Gbs, though I haven't actually confirmed that. It works well enough for my purposes of transferring text documents and the occasional batch of vacation photos to my external SSD. Conclusion This hub from Anker is rated at 10Gbs which is plenty for me. But if you regularly transfer large amounts of data (like for video editing), I would instead recommend a powered docking station such as those from CalDigit. But for me, this portable hub does everything I need, and for much less money.

Almost perfect, could use one more USB-C Gen 2 port and a metal case instead of plastic.
Never really had any problems with Anker gear, I've come to trust the brand name. This little hub is almost perfect for use with my 2019 MacBook Pro, but where Anker really dropped the ball is by not adding one more USB-C port. I mean, there's two, but if one is dedicated to power devices only that doesn't really leave much room for expansion by only giving you one extra, I mean they were thoughtful enough to give you two USB-A ports. I do like that the USB-C and two USB-A ports are version 3.2 Gen 2 rated for up to 10Gbps transfer speeds versus Gen 1 at 5Gbps. The plastic casing does get hot, not sure if aluminum metal would be any better, but it would feel nicer, plastic just feels cheap. Also, a dark case with dark letter printing doesn't work because you can't see the writing, should have used lighter letter coloring. Otherwise, solid performer. I'll keep it along with my other one because having two hubs with a laptop is convenient so I don't have to always haul a hub around from place to place. PROS: • 1 USB-C port version 3.2 Gen 2 rated up to 10Gbps. • 2 USB-A ports version 3.2 Gen 2 rated up to 10Gbps. • Also includes, HDMI, Ethernet, SD and micro SD card ports. CONS: • Plastic casing, gets hot. • Should have one more USB-C port. • Port description lettering is too dark, gets lost against dark case color, should have used white or silver lettering instead. • No audio port.

Does everything, super portable, robust construction
This is a super useful hub. I also used the Anker 341 7-in-1 hub for years, and it was very reliable for every feature, and the 555 8-in-1 looks to be of the same quality. The ethernet adapter is a great addition, and it works right away at 1G speeds on Linux 6.18 and even Android 16. I upgraded from the 341 to use this to connect to and configure devices from my desktop without having to drop my normal ethernet connection, and it is fantastic for that. It's a real swiss army hub, perfect travel size, and incredibly handy.

Great as long as you know its limitations; runs warm; monitor settings may need to be changed
I reluctantly gave up MagSafe and joined the USB-C future when my employer issued me a new 2019 16" MacBook Pro. Searching for a way to connect my various peripherals I settled on this hub as a reasonable way to connect a 4K display, pass power from the laptop charger (albeit not the full 96W; macOS reports 79W after hub losses—good enough most of the time), connect 1GigE, and provide a few spare USB ports and occasionally-used SD card slots. I've learned a few things: A port that looks like USB-C does not pass video unless it is a "Thunderbolt" port (look for the lightning bolt logo, apparently); connecting a USB-C-to-mini-DisplayPort adapter to the USB-C port on this hub did not allow my monitor to work. Lesson learned. The HDMI port did work, and did pass 4K@60Hz, but only after I adjusted my monitor settings. At first I was convinced either my HDMI cable or this hub were defective, because macOS would only allow me to select 4K@30Hz. I have an LG 4K display, and from reading forums, one must enable 60Hz in the on-screen display menu before the monitor will tell the computer it is capable of displaying 60Hz video. For my monitor, that meant changing "Ratio" in "Quick Settings" to "Original" (it defaulted to "Wide", with a separate configuration for each port), as well as turning on "HDMI ULTRA HD Deep Color" from "Picture" -> "Picture Adjust." After I changed those two settings, 60Hz was not available until I unplugged the HDMI cable from the hub and plugged it in again. After that I had buttery smooth 4K video at 60Hz. The hub works as advertised, at least for my configuration. The 1GigE port works well, and is equivalent to a direct USB-C to Ethernet adapter I tried. It does run warm to the touch as other reviewers have reported. That's not problematic, but I'd prefer it pass the missing 17W to the laptop rather than dissipate it as heat. Time will tell how well the hub holds up, but for now I'm happy. In summary: if you have a new Mac this hub will likely work for you, though you may need to adjust your monitor settings.
