In summary, a harsh environment can generally be described as a setting in which survival is difficult or impossible. However, there are harsh environments where monitoring CO2 levels is a vital part of the process or is needed to ensure a high level of indoor air quality. Proper CO2 levels enhance process conditions and help ensure the quality of the indoor air. Amphenol Advanced Sensors offers IP65- and IP67-rated enclosures in both single-channel and dual-channel options to allow monitoring of CO2 in harsh environment applications. The sensors are available with or without potting. Sensors can be customized to match the application (commercial consideration required).
