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).

Surprisingly durable
Color: Yellow, Color: Yellow
*** UPDATE/EDIT: I bought this thing back in February 2024 and ten months later with nearly DAILY USE this bad boy is still going strong!! You can see in my video, filmed just now, that it's still in one piece and that despite the frequent play, she still LOVES it. It smells like rubber, which doesn't smell like roses to me... but all rubber toys are going to, and that's ok. I'm just so impressed with the durability. Really, really impressed. Between interest, durability and value, I say if you are looking for this kind of toy you should get it if your dog is an appropriate size. Ten months of daily, hard use of throwing, fetch, chewing, travel, overnights in the elements, you name it. There's no reason not to. It's the perfect chew toy IMHO. *** ORIGINAL REVIEW SEPTEMBER 2024: My Goldendoodle is great about destroying every chew toy I give her. She doesn't ruin shoes, she doesn't counter surf (ok she does, she just doesn't take anything) and she has learned to leave the scrunchies and socks where she finds them. Even the remote is safe. (She'll hide it, but it's not destroyed.) So the chew toys get completely mangled because they get her full attention. This toy? It has survived the worst of her chewing attention. Being a cardiac service dog, she goes everywhere with me, including trips, and this toy always gets packed. It's great to throw because it has a "handle" and chucks really well. She carries it easily, like a pacifier lol. And it somehow has survived. It's a bit of a challenge to get treats inside, so if your goal is to stuff it frequently, this might not be the right toy. But it's possible. As for durability, this has been in the top two or three for my girl. Worth the money. Keeps her entertained, which is important, lol...

Durable toy, keeps them busy
Color: Red
our trainer said our dogs needed cognitive toys and lick toys to help them calm down. I had doubts about this toy. I was pleasantly surprised when it kept them entertained off and on throughout the day. One would take a break and the other would start batting it around and licking at it. I squished some soft treats into the stem section, crunch treats of various size into the top hole (a couple freeze dried chunks of chicken that I know wouldn't come out easily), and mashed some squishy sweet potato treats into the side holes of the top. While it did take a bit of time to prep with all the different types of treats, it really kept them entertained for a long time. They are 40 pounds and decent chewers and haven't bitten off any rubber bits. Very durable.

Favorite toy of all time
Color: Red
I have had my dog for 12 years and this is truly the BEST toy I’ve ever bought her (and I’ve bought probably hundreds). I squish the soft-style treats into the holes and it keeps her occupied for a good chunk of time. She loves it. I usually do it multiple times a day with a few different types of treats. She is an extremely aggressive chewer and has never damaged this toy. Now that she’s older I’m especially appreciate of this toy because it keeps her brain active and gives her something to do when she’s not feeling up to a walk.

Tough toy but even tougher to get clean!
Color: Red
My puppy is an aggressive chewer and he was only semi-interested in this toy. It hasn't been my favorite, either, due to it being pretty difficult to clean thoroughly. The toy is, however, very durable and its thick rubber has held up to the many bounces on hard floors and tough chew sessions it's been subjected to over the past few months.

A pup favorite and has held up well!
Color: Yellow
My adult dogs really like this treat feeder and love working to get the goodies out of it! It’s held up well over many months despite their biting and gnawing on it, so a good purchase overall. It’s also different than the usual Kongs so adds some variety to their feeder puzzle repertoire to keep up the diversity of mental stimulation.
