We are offering ph meter. Ph meter is a digital display ph meter, which uses blue backlight, double digital display, can display the ph value, temperature value or potential (mv) values.the instrument applies to universities, research institutes, environmental monitoring, industrial and mining enterprises andother departments of the laboratory sample to measure the ph of the aqueous solution and the potential (mv) values, coupled with the orp electrode measurable solution orp (oxidation - reduction potential) values , coupled with ion-selective electrode to measure the value of the electrode potential of the electrode.
