Conductivity Meter

P-523 Portable Conductivity/DO Meter

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. There is optional carrying case.
