The measurement of dissolved carbon dioxide (excluding HCO3 – and CO3 2-) in water is one of the most important parameters for water monitoring.
The sensor is designed to be interfaced externally to CTD probe systems, to own measuring systems or as stand alone sensor.
CO2 sensor
Description
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
