Environmental Applications

Reliable ORP monitoring capabilities can be crucial to environmental sensing devices and can help enable early detection of redox changes in natural waters, waste streams or remediation zones.

Understanding ORP Measurement

Oxidation-reduction potential (ORP) reflects a solution’s ability to either donate or accept electrons, which is an indicator of its chemical reactivity. Sentron’s solid-state ORP sensors are easily integrated into OEM devices and platforms and can be configured with pH, EC and temperature sensors. This enables multiparameter measurement within a single system for faster response times and a more complete picture of a chemical environment.
