DO Sensor – Dissolved Oxygen
The oxygen sensor measures the dissolved oxygen in the water. The measuring principle is optical. It is based on an LED that excites an oxygen-reactive membrane and detects its oxygen-dependent luminescence emission by means of a photodiode.
This sensor measures the dissolved oxygen in the water. The measuring principle is optical and is based on an LED that excites an oxygen-reactive membrane and detects its oxygen-dependent luminescence emission by means of a photodiode.
The key features:
- Dissolved oxygen measurement
- Optical technology
- Temperature sensor for automatic temperature dependent compensation of the oxygen measurement
