ORP-1000L Logging Oxygen Reduction Potential Sensor

Designed to operate on a remote power source for long periods of time, the ORP-1000L is able to operate long term with minimal field servicing, allowing for unattended operation.

Applications include monitoring of:

  • Streams and rivers
  • Water and wastewater treatment monitoring
  • Groundwater analysis and industrial water process monitoring – and many more!


ORP-1000L – Submersible oxygen reduction potential Sensor

The ORP-1000L is a submersible oxygen reduction potential (ORP) sensor designed and manufactured in Australia. With a multitude of ORP sensors deployed throughout Australia and the world, the ORP-1000L is proven to withstand harsh field conditions.

The ORP sensor only requires a low voltage power despite being fitted with an internal logger.

The internal logger allows the ORP sensor to be left in the field for an extended period of time. It is also possible to fit an onboard battery pack for times when power supplies cannot be provided.
