Hanna HI98127 pHep 4 pH & Temperature Tester – 0.1 pH

The Hanna HI98127 pHep 4 pH and temperature tester is a compact waterproof meter for portable pH testing in school laboratories, environmental fieldwork and general laboratory applications. It measures from -2.0 to 16.0 pH with 0.1 pH resolution and automatically compensates pH readings for temperature.

The dual display shows pH and temperature simultaneously, while automatic calibration and a stability indicator help make routine measurements straightforward. The replaceable HI73127 pH electrode allows the electrode to be renewed without replacing the complete tester.
