Product Description

Measurement of parameters such as pH, mV, conductivity, TDS, salinity, resistivity and temperature of water solution, the most cost effective portable analytical instrument.


Features

● 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.
