Multiparameter Water Quality Meter with printer

SALIENT FEATURES: • PH MODE: Up to 5 points push-button calibration with auto-buffer recognition . Selectable pH buffer Standards(USA, DIN, NIST. Automatically calculates and display electrode slope that help you decide whether to replace pH electrode. calibration due reminder prompts you to calibration the meter regularly. • ORP MODE : Absolute or Relative mV measurements provides accurate ORP measured value 1 point offset calibration allows user adjusts displayed to a known standard. • CONDUCTIVITY /TDS/SALINITY/RESISTIVITY MODE : Up to 5-point push-button calibration allows user to users customized calibration solutions. Default 10uS, 84uS 1413uS, 12.88mS and 111.8mS) Adjustable TDS conversion factor ,cell constant ,temperature coefficients and 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 measurements standards. (ppt)
