CLR Combined ORP electrode, annular Pt sensing element, Salt bridge gel electrolyte
The Mod. 201GELxD series are advanced combined Oxidation-Reduction Potential (ORP) electrodes featuring an annular platinum sensing element. Engineered for both laboratory and industrial environments, they are seamlessly compatible with immersion and through-flow probes.
Equipped with a highly reliable salt bridge and a gel reference, these electrodes deliver exceptional performance in applications with good water conductivity. They are specifically designed to handle high dosages of oxidizing or reducing substances while requiring minimal maintenance.
Key Advantages
- Maintenance-Free Design: The gel-filled reference eliminates the need for any electrolyte refilling, saving time and operational costs.
- Superior Poisoning Protection: A double-junction reference system with a salt bridge protects the internal electrolyte even in harsh, chemically demanding conditions.
- Passivation Resistance: The robust annular platinum measuring electrode ensures high stability and resistance against passivation.
- Easy Integration: Features industry-standard dimensions (12 mm diameter, 120 mm length) for direct drop-in replacement.
- Ready to Use: ORP electrodes do not require calibration before use (standard ORP solutions are available for chain verification).
Important Configuration Notes
To ensure your custom electrode can be manufactured, please check these 2 rules:
S7 SCREW & SS FLANGE CONNECTORS: You must select No Plug. These are bare mechanical interfaces without factory cables. (Note: S7 external cables are sold separately).
EXPLOSION-PROOF (EX) HEADS: You must select No Plug. Industrial Ex-proof safety standards require bare wire installation; standard plugs cannot be attached.

Calibration & Care Guide
- No Calibration Required: Unlike typical pH sensors, ORP electrodes do not require any manual calibration prior to installation or operation.
- System Verification: While calibration is unnecessary, standard ORP solutions are available to periodically check and verify the accuracy of the entire measuring chain.
- Zero Maintenance Design: The sealed gel-filled reference eliminates the need for any electrolyte refilling, drastically reducing operational downtime and labor costs.
