Hanna Instruments HI98118 GroLine Waterproof Hydroponic pH Tester
Our newest pocket meter for measuring the pH of a hydroponic nutrient solution is the GroLine HI98118 pH/temperature tester. This sleek meter is only 0.7′ thick and extremely ergonomic, fitting comfortably in the palm of your hand. The HI98118 features a large, easy-to-read LCD display that displays pH and temperature as well as calibration, stability, and low battery indicators. All operations have been reduced to two buttons. One toggles the meter on and off, while the other performs automatic one or two-point calibration.
