AquaSensors Optical DO Sensor
- 0 to 20ppm measurement range
- No membranes-only annual field replaceable caps
- Plug & Play Suitable for telemetry, dataloggers & PLCs
- ModBus output
Overview
The AquaSensors Optical DO Sensor can be connected to any computer to view data, calibrate the sensor and customize measurements without the need for an additional electronics box.
The Optical Dissolved Oxygen Sensor can be connected directly to a PLC for seamless integration with any industrial control system.
An optional AV38 or AquaPro local display / controller is available to provide a versatile system for more conventional installations. This option offers single or dual sensor inputs. It provides an ideal solution for monitoring all dissolved oxygen levels throughout a wastewater treatment plant.
The optical dissolved oxygen sensor covers a measurement range of 0 to 20 ppm and features a plug and play design with digital interface. No membranes are required for the sensor, just a simple, once a year cap replacement.
There is no cross sensitivity to carbon dioxide, sulphide, sulphate, ammonia, chloride or hydrogen sulphide.
