P-523 Portable Conductivity/Dissolved Oxygen Meter by Peak Instruments

Measure conductivity, TDS, salinity, resistivity, dissolved oxygen and temperature of water solutions and very cost effective.

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.
