Multi parameters PH Meter for Water Testing Lab

Multi parameters PH Meter for Water Testing Lab

Automatically identify 13 kinds of pH standard buffer solutions. There are three series of standard buffer solutions to choose from: European and American series, NIST series and Chinese series; Automatically identify 8 kinds of conductivity standard solutions.

High purity water pH measurement mode and ammoniated pure water pH measurement mode can be set

pH measurement supports 0 ~ 100 ? automatic temperature compensation; The conductivity measurement supports 0 ~ 50 ? automatic temperature compensation, and the conductivity measurement mode has the function of high-purity water nonlinear temperature compensation; The dissolved oxygen measurement mode has the functions of 0 ~ 45 ? automatic temperature compensation, 0 ~ 45 ppt automatic salinity compensation and 66 ~ 200 kPa manual air pressure compensation.

Equipped with three compound pH electrodes, conductivity electrodes, ORP electrodes and polarographic dissolved oxygen electrodes.

400 sets of data storage

The multi parameters pH meter uses advanced conductivity measurement technology. The conductivity electrode with constant K=1 only needs one point calibration to meet the measurement accuracy requirements of 0.5?200ms/cm.

The multi parameters ph meter complies with IP57 waterproof grade and is equipped with calibration solution and suitcase.

Switchable pH, dissolved oxygen, conductivity, ORP, TDS, salinity and resistivity. TDS and salinity are calculated by polynomial to ensure the conversion accuracy of the full range

The polarographic dissolved oxygen electrode with new structure can measure temperature, salinity and dissolved oxygen at the same time. Equipped with a special dissolved oxygen electrode calibration sleeve, the electrode polarization takes only 3 ~ 5 minutes.
