The measurement of dissolved carbon dioxide (excluding HCO3- and CO32-) in water is one of the mostimportant parameters for water monitoring. The T28ACO2 now a new membrane covered optical CO2 sensor with titanium housing and other improved characteristics. So the new T28ACO2 sensor is designed for depths of up to 1,000 m, has an analogue or digital output, a reduced current uptakeand includes an automatic internal temperature compensation. The sensor is designed to be interfacedexternally to CTD probe systems, to own measuring systems or as stand alone sensor

The measuring principle:
The inner sensor volume is separated from the sample by means of a gaspermeable silicone membrane. Liquids and solids are not able to pass themembrane. If the sensor is dived into a sample, the CO2 partial pressure equali-sation is achieved between the inner sensor volume and the sample. Inside thesensor there is an optical sensor mounted. It's working principle is based on theSingle-Beam Dual Wavelength NDIR. This measurement of the CO2 partialpressure has to be accompanied by the measurement of the temperature in thewater and by the air pressure for calculating the carbon dioxide concentration.
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
- with internal temperature compensation
- compensation of humidity and other influences
- heated sensor head to avoid condensation
The optical carbon dioxide sensor has some advantages compared with the so called m-method, becausethere are no signal interferences to silicate, phosphate, HCO3- and CO32- as found in a comparison.
