Hanna Instruments HI98318 GroLine Waterproof EC/TDS (ppm) Tester
Our newest pocket meter for measuring the EC/TDS of a hydroponic nutrient solution is the HI98318. This sleek meter is only 0.7′ thick and extremely ergonomic, fitting comfortably in the palm of your hand. The HI98318 has a large, easy-to-read LCD display that shows EC or TDS as well as 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-point calibration.
- Quick Calibration Mode Using Hanna pH/EC Quick Cal Solution
- Graphite Sensor for Reduced Polarization Effect
- Two-Button Operation
