This highly precise, stable and accurate dual beam infrared carbon dioxide (CO2) sensor is ideal for integration into a CO2 incubator or other gas cabinet.

Contact us today to discover how our range of carbon dioxide sensors are the perfect fit for your laboratory.


This highly precise, stable and accurate dual beam infrared carbon dioxide sensor supplied in an aluminium housing 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 5S3 carbon dioxide sensor can be used in laboratory incubators to ensure process gases are maintained and monitored at all times. As an example, the 5S3 (along with the MIR carbon dioxide sensor) are used in cell culture incubators to help aid the cell cultivation process and tissue culture storage.


The 5S3 carbon dioxide sensor is used within some Analox products including our SDA carbon dioxide monitor but as an OEM solution it is utilised by other analyser manufacturers and as an ambient carbon dioxide sensor connecting to a control panel.
