Portable pH/Conductivity Meter

Portable pH/Conductivity Meter
Model: ELE-723

Introduction:

Double-parameter meter, equipped with pH electrode and conductivity electrode, automatic identification of electrode by meter.
Built-in microprocessor chips, intelligent functions such as automatic calibration, automatic temperature compensation, data storage, function set-up, self-diagnose information, automatic power-off and low voltage display.
Automatic identification of 13 pH standard buffer solutions, three options of standard buffer solutions: Europe and America series, NIST series and China series.
Able to set pH measurement modes of high purity water and pure water with ammonia.
Automatic identification of 8 conductivity standard calibration solutions, two options of standard calibration solutions: Europe and America series and China series.
Adopt advanced conductivity measurement technology, use conductivity electrode of constant K=1, only need one-point calibration and meet the measurement precision requirement of 0.5μS/cm ~ 200 mS/cm.
Ability to switch among conductivity, TDS, salinity and resistivity. Multinomial calculation for TDS and salinity to ensure the conversion precision of the full scale.
Conductivity measurement mode has the function of non-linear temperature compensation for high purity water.
Meter meets IP57 rating, equipped with calibration solution and portable case.
