Hanna PH and Alkaliinity Checkers

[William Morris]

Looking for input on these checkers. Thinking of purchasing both of them.

Love my alk tester. Fast and easy little device to use. Can’t comment on the PH tester.

i have Hanna Cal and Alk as well as others, love them, easy and repeatable results.

Some people find Hanna Cal and DKH inconsistent, they are very consistent in my exp, cleanliness is a must, using meniscus curve in the cuvette correctly is a must also.
Do get the calibration set, that way any spurious results can be referenced, also get some spare cuvettes, over time staining although may not be seen to the human eye, will affect readings and is easily curable by cuvette replacement.

Hanna relies on user accuracy, cleanliness and attention to detail, if you can accommodate these things imo they are a godsend.

I have been using the Alk test for sometime now and really like it. As @Lightspeed suggest cleanliness is a must. keeping the reagent clean of residual reagent will give a more reliable test. I use a piperator and new pipette tips for all the tests.

What is your source for the piperator and tips?

I have used the alk for 5 years now and its been very consistent.
Bottle to bottle may be off .2-.3 at times.

Always have a backup test for anything you test for.

I have an old Hanna ph/tds tester. It must be 15+ years old.
Probably on my 4th probe by now.
I used it for years in hydroponics.
I also have a milwaukee with a apex probe. Both read the same if kept in storage solution and calibrated.
I also have a milwaulkee tds meter to verify ro/di above and behond you unit.

I have the PH tester. I use it as a sanity check against my GHL probe.

So far so good. Easy to use. Seems accurate. I do find that 10mls of water is a lot for one test. That would be my only complaint.

Amazon.

Would you mind providing a link to Amazon for what you use?

I can’t say how accurate they are, but I am a self diagnosed color blind. I always have to have my wife look at the color charts for me on the Red Sea kit. So I love my Hanna checkers. Gives me numbers I can understand and I’m just going to say it’s a ballpark and close enough for government work. The pH stick I have seems slow and off compared to my Apex even after calibrating both at the same time. (https://www.saltwateraquarium.com/h...3pXOQR10jFytX3rW-cs0IEG1STcvhiSBoC6B4QAvD_BwE)

Alk is amazing. If you were going to buy two I would probably do ULR phosphate/phosphorus over pH, but that's just my opinion.
