External Sidestream CO2

External Sidestream Capnograph Module

Part # SGSE

Our capnography technology is available in inexpensive and reliable mainstream or sidestream versions for manufacturers of patient monitors, anaesthesia machines and ventilators.

SensoGas-SE external sidestream capnograph module is an excellent plug and play alternative module to added to your designs for your CO2 gas analysis needs. It can replace seamlessly competing sidestream capnograph modules on the market, consult us for details.

It is used in conjonction with our new PFSA polymer sampling line that takes off the humidity allowing long working hours without replacement of the sampling line. Pump lifetime is prolongated thanks to the detection of  the sampling line presence. When the sampling line is not present, the pump would simply go in standby.
