The HI9814 is a slim, lightweight, and waterproof portable meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature with a single amplified probe. The meter operation is simplified with two buttons. One is used for on/off and for calibration while the other is used to switch between the measurement modes. The HI9814 has advanced features including an 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
• Conversion Factor (CF) selectable between 0.5 (500 ppm) and 0.7 (700 ppm)
