RWT O95A – Fluorescence Dissolved Oxygen Sensors

RWT O95A – Fluorescence Dissolved Oxygen Sensors


The Australian made RWT O95A is the next generation in Fluorescence Dissolved Oxygen measurement. We have taken a sensor that was already good and made it better.

  • Description
  • Features
  • Technical specifications

The RWT O95A is the latest development in Dissolved Oxygen technology, where engineers prefer fluorescent dissolved oxygen measurement. We have redesigned a fluorescent Sensor to be compatible with existing Royce Water Technologies assemblies and mounting systems.
The RWT O95A is a SMART optical dissolved oxygen (DO) sensor for use in water and wastewater applications. Combines high reliability with low maintenance. Standard 12 x 120 mm design.
