KETOTEK pH Meter Digital Water Quality pH Tester Pen with Calibration Solution 0-14pH Portable Water pH Test Kit for Hydroponics Fish Tank Batteries Included

Good quality pH metre. Calibrated and works fine

easy to use, I haven't checked accuracy yet but it's definitely value for the money

Worked brilliantly for a month, using twice a week. Then battery died and when I changed them, the digital reader no longer works.

Took a long time for what it did, as you have to calibrate it. Needs distilled water. Very fiddly and complicated for a supposedly simple procedure. I'm trying PH strips next time.

Needed for liquid ph reading

Product it self is very nice the only problem I changed batteries the unit stopped working, tried several batteries still no joy.

"Easy" to use, but useless. Really too inaccurate! If you pop it into 6.86ph buffer, hold calibrate you expect it to read about 6.86. No. It reads say 6.36. A huge error when looking to get a pool into the right pH range. 😡

Product as described cannot fault anything great purchase speedy delivery would highly recommend
