Lab Equipment  PHS-3B Precision PH Meter 

The Model pHS-3B pH meter is a 3 1/2   digit decimal pH meter with ATC (auto temperature compensation) or MTC (manual temperature compensation). It can measure the temperature of the medium to be measured and display the values of temperature, pH and mili-voltage It is suitable to measure the pH value of aqueous solution and the potentials of electrodes in laboratories of research institutes, factories and mines. If it is equipped with an appropriate ion selective electrode, it can be used as a terminus display device for potential titration.
