Up to three electrodes can be connected to the meter simultaneously for the measurement of multiple parameters, including pH, conductivity, TDS, temperature, and ORP.ORP measurement is available in mV mode with an ORP probe connected (model 301Pt-C, sold separately).Easy CalibrationQuick and easy 1- to 3-point auto. calibration, recognizing pH standards of 1. 68, 4. 00, 7. 00, 10. 01, and 12. 45; conductivity standards of 1413 µS, 12. 88 mS, 84 µS, and 111. 8 mS.The slope data will be displayed after completing 2nd and 3rd point calibration, indicating the condition of your pH electrode. The self-diagnosis function ensures calibration will be properly performed.Easy Parameter SetupAuto. lock and auto. power off function available.pH standard series, pH resolution, stability criteria, temperature unit, conductivity cell constant, reference temperature, and temperature compensation coefficient are all customizable. TDS conversion factor can be set from 0.40 to 1.00.Built ToughThe IP57 water-resistant structure makes the meter ideal for use in harsh environment. The rubber sleeve protects the instrument from general impact and gives you a firm grip.Large LCD DisplayStability icon. Take the reading when the smiley face stays on screen.Icons for finished calibrationsSimultaneous temperature displaySuitable for lab-use as wellThe foldable stand allows use as a benchtop meter.
