PH MODE: Up to 5 points push-button calibration with auto-buffer recognition. Selectable pH buffer standards, (USA, DIN, NIST, User-defined) o o resolution (0.1, 0.01, 0.001pH )temperature units ( C or F) Automatically calculates and displays electrode slope that helps you decide whether to replace pH electrode.Calibration due reminder prompts you to calibrate the meter regularly

ORP MODE: Absolute or Relative mV measurements provides accurate ORP measured value .1 point offset calibration allows user adjusts displayed value to a known standard.

CONDUCTIVITY/TDS/SALINITY/RESISTIVITY MODE: Up to 5-point push-button calibration allows user to uses customizedcalibration solutions. Default 10uS, 84uS, 1413uS, 12.88mS and 111.8mS)Adjustable TDS conversion factors, cell constants, temperature coefficients and o o normalization temperature. (20 C or 25 C)Allows user selects linear or pure water temperature compensation modes.In salinity measurement modes, selectable practical salinity (PSU) or seawater measurement standards. (ppt)

• Selectable either temperature units between degrees Celsius ( C) and degrees Fahrenheit ( F)
• Automatic Temperature Compensation (ATC) ensures high accuracy of measurements
• Automatic endpoint function freezes the stable measured values for easy reading and recording data.
