Scope of application
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.
Function characteristics
1. pH meter with LCD, Chinese operation interface;
2.pH meter using microcontroller automatic control experiment without human duty;
3.pH meter assay changes in various parameters, automatic test results;
4. pH meter has a self-diagnostic function, suggesting operating functions.
