The determination of dissolved oxygen in water is based on the optical technology of luminescence.
Drift-free, optical measurement
Easy, intuitive handling
Matches BOD bottles
Drinking/ Potable Water
This technology offers concrete advantages concerning low maintenance, easy calibration and a fast response combined with high accuracy.
For oxygen measurement based on luminescence there is no electrolyte required. So it is not necessary to refill the sensor which makes maintenance simple and easy.
No sample flow is needed.
No costs caused by electrolyte.
No pollution of ambient medium.
Long-life sensor membrane.
Insensitive to toxic gases.
Available with a 1.5m, 3m or 10m cable.
Waterproof sensor IP 67.
Internal data storage.
Software for monitoring and storage of data.
Matches bottles 16,4 mm ø and above.
