P-520 Portable PH /Conductivity Meter by Peak Instruments

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. There is optional carrying case.
