Welcome: U-THERM INTERNATIONAL (H.K.) LIMITED
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.
