Basic Info.
Product Description
1. The Optical Dissolved Oxygen technology is based on luminescent optical technology. The Optical Dissolved Oxygen sensor is approved by the ASTM International Method D888-05.
2. Without calibration requirements and thanks to an ultra low power technology, the Optical Dissolved Oxygen sensor meets the demands of field works and short or long term campaigns.
3. Without oxygen consumption, this technology allows you an accurate measure in all situation and especially in very low oxygen concentrations
Applications :
Urban wastewater treatment Industrial effluent treatment
Surface water monitoring,
Sea water monitoring, fish farming, aquarium
Drinking water
