  2 Description General The instrument is used for measuring/controlling the pH, ORP or NH (ammonia) concentration. The function is switchable on the instrument itself. Depending on the measured variable, combination electrodes (e. g. pH/ORP combination electrodes, gas-sensitive sensors) or split versions (glass/metal electrodes with a separate reference electrode) can be readily connected.
