Hanna Instrument HI98131 GroLine Hydroponic Waterproof Pocket pH/EC/TDS/Temperature Tester
With a selectable EC to TDS conversion factor, the HI98131 measures pH, conductivity (EC), total dissolved solids (TDS), and temperature. The pH readings have a resolution of 0.01 and an accuracy of 0.05 pH. The EC and TDS readings have a resolution of 0.01 mS/cm and 10 ppm (mg/L), respectively, and a 2% full-scale accuracy. The HI98131 has an EC range of 0.01 to 6.00 mS/cm and a TDS range of 0 to 3000 ppm using a 0.5 conversion factor or 0 to 3999 using a 0.7 EC to TDS conversion factor.
- One meter can measure pH, EC/TDS, and temperature.
- Quick Cal Mode allows you to calibrate pH and EC/TDS with a single solution.
- The TDS Conversion Factor can be set between 0.5 (500 ppm) and 0.7. (700 ppm)
