Description
The SD 400 Oxi L allows measurement of dissolved oxygen at an advanced level. The determination of dissolved oxygen is based on luminescence. This technology offers distinct advantages regarding low maintenance, easy calibration and fast response combined with high accuracy.
For oxygen measurement based on luminescence, no electrolyte is required. There is therefore no need to refill the sensor, making maintenance particularly easy.
