Pem-Tech Inc. designs self-contained carbon dioxide sensors that utilize infrared sensor technology. Sensor specifications include a measuring range of 0-5 percent, 0-10 percent, or 0-50 percent; repeatability of plus or minus 2 percent, and input power of 14-28 VDC. All of the sensors' electronics are housed in an explosion proof instrument box.

Detcom manufactures several series of industrial gas detection sensors including carbon dioxide-detecting infrared models. The sensors are waterproof, corrosion proof, vibration proof, and feature multi-layer surge protection along with 4-20mA output.
