    HI GroLine Hydroponic Waterproof Pocket pH/EC/TDS/Temperature Tester

    The HI98131 measures pH, conductivity (EC), total dissolved solids (TDS), and temperature with a selectable EC to TDS conversion factor. The pH readings are displayed with a 0.01 resolution and with an accuracy of ±0.05 pH. EC and TDS readings are displayed with a 0.01 mS/cm and 10 ppm (mg/L) resolution and 2% full-scale accuracy. The EC range of the HI98131 is from 0.01 to 6.00 mS/cm and TDS is from 0 to 3000 ppm using a 0.5 conversion factor or 0 to 3999 with a 0.7 EC to TDS conversion factor.

    • 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)

    Simplified one-button calibration

    One or two-point pH calibration is automatic to a pre-programmed buffer set (4.01, 7.01, and 10.01) or single-point pH and EC calibration with the Hanna Quick Cal calibration solution. 

    HI73127 Replaceable pH electrode

    The HI99131 is supplied with the HI73127 replaceable pH electrode. This electrode features an extractable junction that can be pulled 1/8" out to clear any clogging that results in drifting and erratic readings.
