Digital ph tester

Emarley · May 20, 2019

Hello fellow reefers,

Can anyone recommend a good reliable ph digital tester, I have defective colour vision so struggle to read colour test kits. After starting a thread and talking to other members on here I have now ordered hanna checkers for alk, phosphate and calcium, but also want to purchase a reliable ph tester.

Thanks in advance

Dom

Pinpoint ph meter is pretty good and reliable. You will have to calibrate ~monthly or so regardless of which one you get.

If you don’t want to spend that much you can get a cheap one on amazon for ~$20 that will work well too. Just again make sure to calibrate.

Fwiw, the only digital ph tester I've tried was from Amazon and I think I paid around $20. It worked for about a month and then wouldn't calibrate, I ended up throwing it away

Sorry for the newbie question, how do you calibrate?

You'll need to buy calibration fluid. Dip the probe for about a minute until the reading stabilizes (shake gently to get rid of the bubbles) and make adjustments on the meter usually with a small screw.
