P-511 Conductivity Meter

P-511 Conductivity Meter

Measure conductivity, TDS, salinity and resistivity of water solutions, suitable for industrial and mining factories, water treatment engineering and environmental protection, especially for outdoor use.

Main Features:

●Large LCD screen with controllable white backlight.

●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 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.

●Humanized designs like rack and skid proof shell make it more convenient for users.

● Plastic conductivity electrode with automatic temperature compensation to ensure fast and accurate result.

● Grade IP57 and provide optional carrying case.
