GroLine HI9814 Hydroponics Waterproof pH, EC, TDS, Temperature Meter

The HI9814 is a slim, lightweight, 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 has two-button operation, one for turning the meter on/off and calibration while the other switches 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)
