The RDO sensor uses the RDO Technology, which is the EPA-approved method for optical DO measurement. It provides accurate dissolved oxygen (DO) measurements to streamline monitoring in a variety of applications.

The dissolved oxygen probe is designed for use with the Aqua TROLL 500 and  Aqua TROLL 600 multiparameter sondes, one of several interchangeable sensors that can be switched out even when wet.

  • Dissolved oxygen measurement from 0 to 50 mg/L
  • Rugged DO probe design for a variety of surface water, municipal and aquaculture applications
  • DO sensor adheres to EPA-approved In-Situ methods: 1002-8-2009, 1003-8-2009, 1004-8-2009
  • Simplified compliance: EPA-approved optical RDO method makes it easy to comply with Clean Water Act and NPDES permit requirements.
  • Accurate data: Internal data quality IDs ensure you can trust your data.
  • Long-lasting performance: Rugged design stands up to harsh conditions and process environments, with extended life cap to minimize maintenance.
  • Easy data collection: Use either the RDO-X for rugged environmental conditions or the fast responding, Fast Cap for spot checking
