GSS CO2 Sensors, Improving Your Indoor Living Space ...

We discuss GSS sensor solutions used specifically in monitoring indoor air environments. ... When there is no CO2 in the chamber, all the IR light will reach the detector. The greater the concentration of CO2 in the gas sample, the greater the IR light absorbed at the energy and the less IR light that is detected by the IR detector. Using this precise measurement principle, enables CO2 sensors ...

IR vs TC: Settling the CO2 sensor debate once and for all ...

26/07/2016· We clearly understand that CO2 incubators maintain specific levels of CO2, temperature, and humidity for optimum cell growth. These parameters are monitored and controlled via sensors. As for CO2, there are two types of CO2 sensors commonly found in incubators: the TC (thermal conductivity) sensor and the IR (infrared) sensor. But which one is better for accurate CO2 reading and precise …
