The mV mode is used with an optional ORP electrode for the determination of oxidation or reduction potentials of a solution. Hanna offers a variety of ORP electrodes from glass to PEI plastic body styles.The HI9125 uses the universal BNC probe input for pH and ORP electrodes. The universal BNC connector allows the user to select from a wide variety of electrodes based on their particular application. A separate RCA connector is used for a thermistor temperature probe. The temperature probe provides for a high ±0.4°C accuracy measurement for precise temperature compensation.
