Overview
Enviro Test Construct Automatic Calibration Automatic Data pH meter is a digital display PH ORP meter, with LCD digital display, which can display PH and temperature values simultaneously. The instrument applies to the labs in junior college institutions, research institutes, environmental monitoring, industrial and mining enterprises and other departments or field sampling to determine the aqueous solutions’ PH values and potential (mV) values. Equipped with ORP electrode, it can measure the solution’s ORP (oxidation-reduction potential) value; equipped with the ion specific electrode, it can measure the electrode potential value of the electrode.
