Measure conductivity, TDS, salinity, resistivity, dissolved oxygen and temperature of water solutions and very cost effective.
Main Features
●Large LCD screen with controllable white backlight.
●Humanized designs like rack and skid proof shell make it more convenient for users.
●Double-parameter and equipped with DO electrode and conductivity electrode, can recognize electrode automatically.
●Built-in microprocessor chip with functions of auto calibration, auto temperature compensation, data storage, function setup, self-diagnosis, auto power off, low voltage display.
●Auto recognition of 8 standard conductivity solutions, and there are two options for standard solutions: USA series and China series.
●Adopt advanced conductivity measurement technology, one point calibration of conductivity electrode can meet the measuring accuracy requirements for test 0.5μ S/cm ~ 200mS/cm.
●Able to switch between conductivity, TDS, salinity and resistivity. Multinomial calculation for TDS and salinity to ensure the conversion precision of the full scale.
●Conductivity mode has the function of non-linear temperature compensation for high purity water.
●Measurement mode of dissolved oxygen has the function of automatic temperature compensation, automatic salinity compensation and manual air pressure compensation.
●New structure polarographic DO electrode can measure temperature, salinity and dissolved oxygen simultaneously and equipped with special DO electrode calibration sleeve, only need 3~5 minutes for polarization.
●IP57 and equipped with calibration solution and carrying case.
