Review on ๐ฌ MEKBOK Digital PH Meter Tester: High Accuracy for Water Aquariums, Pools, Hot Tubs, Hydroponics, and Wine - Push Button Calibration, Large LCD Display by Carrie Williams
Unreliable for pH meter
As soon as I opened the box I knew something was wrong. The instructions that came with the tester showed signs of moisture and rust spots. When I took the instructions out of the storage box, I noticed that there were no calibration reagents for the tester. I tried the tester anyway to see if it works. It turned on briefly, printed 7.3 on hard tap water, and immediately turned off. It looks like the tester needs to be calibrated right out of the case, which I can't do as it doesn't contain any chemicals.
