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 prove 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 (500ppm) and 0.7 (700ppm)
