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

The HI98131 measures pH, conductivity (EC), total dissolved solids (TDS) and temperature with 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) Features Waterproof and floats in water, designed for the humid growing environment Wide pH range of 0.00 to 14.00 pH Automatic Temperature Compensation (ATC), displays temperature in °C or °F Large LCD displays stability indicator, low-battery indicator, and calibration tags HOLD button for easier measurement recording Battery Error Prevention System (BEPS) with three automatic shutoff settings Battery % level at startup
