Does anyone know what the compound for testing KH is? Its my only reagent I use a lot of (with the titrations needing so many drops and all). It only comes in tiny bottles in the commercial kits, I was hoping to get it in a larger quantity

Expensive meters, when you take into account cost of the testing unit and materials.

Those that appear to be low priced meters are actually ads for testing materials!

I think I'd stick with the test tubes and drops of solution instead of dumping a couple hundred on this . . . but that's just me and my budget . . . not sure about your budget . . .

Hi Compensate:

The accuracy (especially long-term) of a cheaper handheld meter would be my main concern.

How long have you had your meter, FF? Do you have to calibrate it regularly? Have you compared its resting results with the typical testing reagent test kits?

Ive had my meter for about 3 months.
I never calibrated it. I dont think there is calibration. I know it works because I have different TDS levels in my certain tanks and my RODI water reads 0ppm.

My test strips read "VERY SOFT" practically showing a 0ppm in all my tanks. If anything they are the things guilty of being inaccurate.


You may be getting these meters cornfused with pH meters which need to be calibrated often.

I calibrate my TDS meter. Takes 2 seconds and a twist of a screwdriver so no big deal there.

There's a difference between TDS and KH though and I beleive Matt's question was directly about KH.

Matt, I have a link somewhere, as soon as I find it, and have a chance to get back here, I'll poste it.

TDS is a combination of KH and GH. The combination of the two is typically spread evenly.

I am all ears if this isnt a reliable way to measure. I got comfortable using the TDS meter instead of measuring buffering capacity (KH)specifically. + I hate test tubes and drops.

I will have to look for the the calibration.

I'll have to read those links when I get a minute. Kh and Gh can be very different though. And your gh measures calcium and Magnesium. TDS will measure sodium, copper, uluminum........

Alright, I found the link. I thaught it would go into more detail, and apprently thaught it answered the question quite well but now see that it doesn't. I poste it anyway just for the heck of it. Wish it helped more.
