The HI-98118 pH/temperature tester is our latest pocket meter for measuring the pH of a hydroponic nutrient solution. The ergonomic design allows this tester to fit comfortably in your hand. The large easy to read LCD display shows both pH and temperature along with calibration, stability and low battery indicators. All operations are simplified to two buttons. One is for turning the meter on/off and the other for automatic one or two point calibration.
