PH Meter Tester Kit, 0.01 Resolution, ATC Function, Auto Calibration-Clearance Price

Better than modt cheap ph pens. The calibration is push button. It also reads to the hundreth, which I've never seen

Did not hold the correct calibration for long —after following the difficult to understand calibration instructionsFrequency of calibration is high which can effect your ph adjustments and can cause problems with you plant growth when not getting a correct readingConstant cleaning between using the different calibration solutions that must be replaced every 3 months at a cost ( $4.50 )The meters that are adjusted with a screwdriver are much easier to work with and hold setting for very long periods of timeThe cheep cost seems to indicate they are fazing out this productTDC makes a very good temperature sensative product I have had great luck with

The device is not water proof, which would seem mandatory for a device for testing water. The calibration is overly complicated. The instructions state that the device will need to be recalibrated if not used regularly or when used often.

Came in a hard storage case. Has to be calibrated frequently according to the instructions. This is used for a water sample test. You don't stick It in the ground

Bought one for my winemaking fermentation to measure the PH level. It just doesn’t work. Thought it was a defective equipment, so I returned and bought another one. No luck on this either. I am not going to waste my time on this anymore.

Its been a good meter

Horrible piece of junk..!!! Do not waste your money on it..!! It will not stay calibrated ..never mind trying to use it .. You will just kill your fish and or plants..!! Factory calibrated my a$$... JUNK.

Useful for testing the water pH level when you have a baby
