PHS Series PH Meter is a digital pH meter with LED double digits display and blue light-black, which displays temperature and pH value or potential and temperature value simultaneously. It is suitable for using in the laboratories of university, research institutes, environment monitoring, factories and mines inspection offices for measuring the pH value of the liquid and potential of the measuring electrode (mV). It can also be used to measure electrode potential with various ion-selected electrode and measure oxy-reduction potential (ORP) value with ORP electrode.
