Description
Overview
GAO Tek digital PH indicator device is PH Meter with large screen, blue backlight and double-row digital LCD. It can measure and display Ph value plus temperature value, or mV plus temperature value. It also can measure ORP value when match with ORP electrode, can measure Electrode potential value when match with ion selective electrode.
