Hanna Phep 5 pH meter, model HI 98128
The Hanna Phep 5 pH meter, model HI98128 (shown in picture) is completely waterproof and even floats. (Yes, we have dropped ours at least once in our boil kettle!). Just like the digital probe thermometer, if your pH meter is handheld, ensuring it is waterproof is (in our opinion) an absolute must. We don't have to worry about humidity from kettles getting into the unit and cleaning it under the faucet is dead simple and worry-free as there is no chance of getting the wrong parts wet.
The Phep 5 model reads to 0.01 pH resolution (+/- 0.05 pH accuracy), includes 2-point calibration for greater accuracy, a built in thermometer, and automatic temperature compensation up to 140F.
The electrode (tip) is replaceable. When brewing approximately once or twice a month we've been able to get 8-9 years out of an electrode. Once the readings start to jump around, it's time to replace it. See Hanna Phep 5 pH meter replacement electrode (part number HI 73127).
Be careful when purchasing as there is a very similar looking Hanna Phep 4 pH meter (model HI 98127) that only reads to 0.1 pH resolution. Make sure to check the model number.
