This highly precisestable and accurate dual-beam infrared carbon dioxide (CO2) sensor is ideal for integration into a carbon dioxide (CO2) incubator or other gas cabinets.

Supplied in an aluminium housing, this carbon dioxide (CO2) sensor includes an onboard, barometric pressure sensor compensating for the effect of atmospheric pressure. It is available in a variety of ranges from 0-5000ppm to 0-100% and can provide either a 0 to 2v or 4-20mA output.

The 5S MkIII (or 5S3) carbon dioxide (CO2) sensor can be used in laboratory incubators to ensure process gases are maintained and monitored at all times. As an example, the 5S MkIII’s are used in cell culture incubators to help aid the cell cultivation process and tissue culture storage.

Our 5S MkIII is utilised as a robust and accurate industrial process gas sensor or as a part of a safety system in applications including laboratory research, commercial diving, agriculture and the beverage industry.

The 5S MkIII carbon dioxide (CO2) sensor is used within other Analox products including our SDA carbon dioxide (CO2monitor as an OEM solution, it is utilised by other analyser manufacturers and as an ambient carbon dioxide (CO2) sensor connecting to a control panel.
