AquaSensors™ RDO™ Pro-X Optical Dissolved Oxygen Sensor

General Details

Continuously monitor dissolved oxygen (DO) in municipal and industrial applications with the Thermo Scientific™ RDO™ Pro-X Optical Dissolved Oxygen Sensor. The RDO Pro-X provides real-time, reliable data through continuous DO monitoring, which helps improve wastewater treatment operations.

Connect this advanced optical DO sensor directly to a PLC for seamless integration with industrial control systems. Use any computer to display data, calibrate and customize the measurement without an intermediate analyzer electronics box. Optional AV38 local display/controller is also available for more conventional installations offering single or dual sensor inputs. This versatile system is ideal for monitoring DO levels from 0 to 20 ppm throughout a wastewater treatment plant.
