Review on πŸ“ˆ Extech PH220-C Waterproof Palm pH Meter: Reliable Cabled Electrode for Accurate Readings by Jennifer Middleton

Revainrating 3 out of 5

Excellent product suitable for pH testing

It was really great. I bought a spare probe just in case, but I didn't have to use it. Two notes: 1) DO NOT pull the dipstick out of the stock liquid, rather unscrew the cap. 2) The automatic temperature compensation uses the reference temperature in the sensor head. That means the sensor head needs to be close to room temperature for it to work (i.e. don't leave it in a cold garage like I did). It will tell HHH when you connect the sensor if the device is too cold. We strongly recommend this product.
