OR4C ORP Sensor
Brand: Yokogawa Electric CorporationPH4/OR4 Sensor Series allows pH/ORP measurement under severe conditions, such as where the process fluid is heavily contaminated or contains sulfide.
PH4/OR4 Sensor Series meets the simple apparatus requirements.
Features- Extremely long life span for ORP measurement in electrolytic process
- With the pressurized inner solution, a pressure holder is not needed
- The reference electrode is composed of silver ion trap which inhibits the generation of sulfide around the ceramic liquid junction
