Description
Features
- The Optical Dissolved Oxygen technology is based on luminescent optical
- Technology
- The Optical Dissolved Oxygen sensor is approved by the ASTM International
- Method D 888 to 05
- 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
- Without oxygen consumption, this technology allows you an accurate measure
- in all situation and especially in very low oxygen concentrations
