Precision PH meter, Nanjing PHS-3B type precision PH meter, Kehuan precision PH meter

PHS-3B precision pH meter

The large screen and dual row digital LCD display screen have automatic or manual temperature compensation function for one or two point calibration. It has automatic calibration function and can manually calibrate electrical connectors below the plane, which helps with corrosion prevention and safety. Suitable for laboratory sampling and determination of pH and potential (mV) values of aqueous solutions in colleges, research institutes, and mining enterprises. In addition, ion selective electrodes can be used to measure the electrode potential of the electrode
