Message InquiryOxidation-Reduction (ORP) Sensor
Technical Features:
● Employs the world’s most advanced annular, large-cross-section Teflon diaphragm, ensuring a stable liquid junction for the electrode.
● The unique structure makes the Sensor less prone to contamination and blockage, with a long service life.
● The reference system is filled with a polymeric polymer, making it extremely convenient to use and eliminating the need to replenish the electrolyte.
● The Sensor is suitable for various highly polluted media and can prevent S 2- , NH 4+ , CN - Interference
● Measurement range: ±2000 mV; temperature: 0–130°C; pressure rating: 0.6 MPa
● When ordering a triple-composite Sensor, please specify the size of the temperature-compensation resistor.
● Temperature compensation resistors: PT100, PT1000, 2.252 kΩ, 10 kΩ, 22 kΩ, etc.
