Membrane covered optical CO2 sensor for monitoring
Online determination of the dissolved carbon dioxide in water
/
The measurement of dissolved carbon dioxide (excluding HCO3- and CO32-) in water is one of the most important parameters for water monitoring. AMT GmbH has developed now a new membrane covered optical CO2 sensor with titanium housing and other improved characteristics. So the new AMT-CO2 sensor is designed for depths of up to 1,000 m, has an analogue or digital output, a reduced current uptake and includes an automatic internal temperature compensation. The sensor is designed to be interfaced externally to CTD probe systems, to own measuring systems or as stand alone sensor.

Main features of the Carbon Dioxide Sensor:
- submersible direct reading sensor for natural and industrial waters and sea water
- detects CO2 and total inorganic carbon when measuring additionally pH
- no signal interferences to silicate, phosphate, HCO3- and CO32-
- built-in reference measurement for superior stability
- calibration coefficients stored internally
- for depths of up to 1,000 m
- less than 0.5 W power consumption
- with analogue or digital output (please select)
- with internal temperature compensation
- compensation of humidity and other influences
- heated sensor head to avoid condensation
