The HI9814 is a slim, lightweight, and waterproof portable meter that measures the pH, conductivity (EC), total dissolved solids (TDS) and temperature of nutrient solutions used in hydroponics, aquaponics and greenhouse growing. The meter operation is simplified with only two buttons. One is used for turning the meter on/off and for calibration while the other is used to switch between the measurement modes. The HI9814 has advanced features including a selectable EC to TDS conversion factor (0.5 – 500 ppm and 0.7 – 700 ppm).
- 3 in 1 amplified probe with pH, EC/TDS and temperature sensors
- Quick Cal Mode to calibrate pH and EC/TDS with one solution
- EC to TDS Conversion factor selectable between 0.5 (500 ppm) and 0.7 (700 ppm)
