There are two kinds of CO 2 gas sensors. The first is the T/C (thermal conductivity) sensor. Thermo Scientific incubators offer a T/C sensor and electronics that are very stable, accurate and economical. In fact, T/C sensors are our most popular method of CO 2 control. They are long-lasting, comparatively inexpensive and robust. An IR (infrared) sensor is preferred for some applications ...
