P-520 Portable PH /Conductivity Meter
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 pH 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 standard pH buffers and there are three series of standard buffers for option: USA, NIST and China.
●Able to set pH measurement modes of high purity water and pure water with ammonia.
●Auto recognition of 8 standard conductivity buffers and there are two series of standard buffers for option: USA series, 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.
●IP57 and equipped with calibration solution and carrying case.
