pH / ORP


BI pH/ORP sensors are based on two different measurement techniques: Conventional combinational and Differential Electrode Measurement Technique (DEMT). Our range of conventional combinational sensors can withstand extreme temperatures from -5°C to 140°C. They have large reference junctions to minimize clogging problems by process media.

Unlike run of the mill pH/ORP sensors we also provide the DEMT sensor technology. These DEMT sensors provide unsurpassed accuracy, reduce reference junction fouling, and virtually eliminate ground loop problems. A field reparable model is also available to reduce downtime. These sensors are certified for use in hazardous areas too.

Our range of analyzers and transmitters come with a wide array of functional capabilities and control strategies to suit your needs.

The 2-wire transmitters are certified by CCOE, Nagpur for meeting intrinsic safety standards to eliminate the need for flame proof enclosures.

For extreme pH and hence difficult to measure applications our success has greatly depended on our retraction assembly. Some of these difficult to measure applications where we have proved our pH/ORP systems are caustic chlorine, enzymatic reactions such as 6APA, malathione, cyanide processing, scrubber for acidic gases, high purity water ….
