Product Specifics:
This is a slim, lightweight, and waterproof pocket sized meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature. 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 HI98131 has advanced features including a selectable EC to TDS conversion factor (0.5 - 500 ppm and 0.7 - 700 ppm).
- 3 parameters, pH, EC/TDS and temperature, in one meter
- Quick Cal Mode to calibrate pH and EC/TDS with one solution
- TDS Conversion Factor selectable between 0.5 (500 ppm) and 0.7 (700 ppm)
