Review on ๐ KETOTEK Digital PH Meter: Accurate 0.01 PH Pen Tester for Water, Hydroponics, Aquariums & More by Ann Thompson
not enough information before buying
I bet it's a good counter. The description explained the calibration process, but for some reason I missed the information about the need to calibrate before almost every use. I got 2 good readings after setting it up, then air registered 16 and water registered 0. I would buy a calibration solution or other method if I had all the information I need.
- great price
- expensive insurance
