1. General
INE-PHS-3E pH meter is a precise digital display pH meter, which adopts double digits
LCD display with a big screen and blue back light. It displays PH value and temperature
value or mV value and temperature value simultaneously. It is suited for measuring pH
value and potential (mV) of water solution in laboratories of universities, institutions and
enterprise. Besides, it can also be used to measure electrode potential with various
ion-selected electrode and measure oxy-reduction potential (ORP) value with ORP
electrode.
