Hanna Instruments checker-fotometer voor Alkaliteit

Een belangrijk onderdeel van water: alkaliteit. Dit is de buffercapaciteit en houdt de pH-waarde stabiel. Als deze te laag is, zorgt de kleinste toevoeging van zuur voor een grote schommeling in de pH-waarde. Als de alkaliteit te hoog is, heeft het toevoegen van zuur (pH+ of -) geen effect meer op de pH-waarde en kunt u deze niet of nauwelijks verhogen of verlagen. Om de alkaliteit accuraat te meten, is de Hanna Instruments fotometer voor Alkaliteit de beste oplossing. Waar teststrips een afwijking van ongeveer 15% hebben, zijn deze checkers erg nauwkeurig en is er nauwelijks een afwijking. Met een paar eenvoudige handelingen en één druk op de knop, brengt u meteen de Alkaliteit in kaart en kunt u bijsturen als dat nodig is.

Aantal tests: Standaard worden druppels voor 25 tests meegeleverd. Daarna heeft u een nieuw flesje druppels nodig.

Hoe werkt de Hanna Instruments checker voor alkaliteit?

Binnen een aantal stappen weet u exact wat de alkalische waarde van het zwembadwater is. Na gebruik schakelt de checker uit, wanneer deze 10 minuten niet wordt gebruikt. Zo gaat de batterij nog langer mee.

  1. Druk op de knop. De meter gaat direct aan en is klaar voor gebruik;
  2. Vul het buisje met 10 ml zwembadwater en plaats deze in de checker;
  3. Druk opnieuw op de knop. De meter staat nu op nul (ZERO);
  4. Haal het buisje uit de meter en voeg 1 ml reagens toe. Dit zijn de druppels die bij de checker zitten;
  5. Plaats het buisje terug in de checker, sluit de deksel en houd de knop voor 3 seconden ingedrukt. De alkaliteit verschijnt nu op het scherm in ppm (parts per million).

They worked out great!!!
Color: D) 4-Pack 3" Balls (Yellow), Color: D) 4-Pack 3" Balls (Yellow)
So far have been the solution we were looking for! I was extremely tired of the non stop destruction and order of large Chuckit balls for our high energy/high drive dog. For about the same price I bought four 3 inch balls to test out their durability and fit for the thrower. THEY WORK! Perfection! They even make a fun whistling sound as they sail through the air. They do require a tad more muscle in the thrower but that is not a problem. They have already shown to be WAY more durable. The 3 inch balls work in the large chunkit thrower. Super find.

Durable
Color: E) 8-Pack 2.5" Balls (Yellow)
My dogs love them. They are very bouncy, and ideal size, and durable. Great alternative to a tennis ball which in my house only last 30 minutes.

Toughest dang balls I ever played with
Color: D) 4-Pack 3" Balls (Yellow), Color: D) 4-Pack 3" Balls (Yellow)
These things are amazing. We have a ball obsessed Husky mix and he has destroyed Kongs, Chuck Its, and a whole lot of other ball shaped objects. These things? We bought the 4 pack because we bought 4 Chuck Its and they lasted a year, all 4 of them only a year, before they were destroyed. A year after buying these? We only bought more because he lost 3 of them. I think we did find one under the dresser after buying this pack... But the others? They either ended up thrown over the fence into the woods or lost in the holes in the yard the monster digs up. Other than a few pockmarks from his teeth and maybe some mud, they may as well be brand new even after a year or two. Probably the most chew resistant thing we've ever bought him. They're really solid rubber and since he hasn't managed to bite into them to take out a chunk, they're safe as hell. Being as big as they are, I don't worry he's gonna choke unattended on them like the usual size of ball. About the only concern is forcing breaks so he can have breathing moments when he manages to talk us into fetch outside. It fits in the larger Chuck It thrower too, so we haven't lost any value from having those torn up.

Sturdy bouncy fun!
Color: D) 4-Pack 3" Balls (Yellow), Color: D) 4-Pack 3" Balls (Yellow)
Great product. My big 70lb Sheppard puppy loves it, hasn’t stopped playing with it since it arrived. She throws it about and chases it, had a good chew on it and even put it in her favorite toys bin. Sturdy, firm and very bouncy. And there are 3 more in the bag for an awesome price. Bright color will make it easy to find and holes thru it will prevent choking and I can string it on a line for training play.

Dogs love these
Color: C) 2-Pack 2.5" Balls (Yellow)
Great quality balls for tough chewers. I love them, but wish the orange ones were available more...I've been checking cuz they are easier to find in the yard than the green that blends in. Our dogs love them and I like the weight for throwing.
