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.
- Two-Button Control
- To Extend pH Electrode Life, Use Hanna Quick Cal pH/EC Calibration Solution
- Extractable Cloth Junction in Quick Calibration Mode.
Features at-a-glance
- Built-in temperature sensor for Automatic Temperature Compensated measurements.
- Renewable junction to clear any clogging that causes readings to drift and be erratic.
- Stability indicator that disappears once a stable reading is obtained.
- Automatic calibration to one or two points at a push of a button.
- Uses Hanna’s Quick Cal pH/EC standard with a pH value of 6.86. The standard can also be used to calibrate conductivity meters to 5,000 μS/cm.
- Battery % level remaining displayed at startup.
- The low battery indicator is displayed when less than 10% battery life is remaining.
