When protecting your employees and operational processes from toxic and combustible gases, it’s critical to choose a gas detector that provides the most accurate and reliable monitoring possible. With so much at stake, using the most advanced technology possible is your best—and sometimes only—choice. Since there are so many types of facilities, gas-detection needs can vary greatly. Some facilities require monitors to identify gases at the lowest possible levels. Other facilities are exposed to gases or compounds that can complicate the ability to detect the gas in question. This is a concept referred to as cross- sensitivity, which will be discussed in more detail later. Still other facilities use combustible gases that require explosion-proof monitors. It is now possible to utilize a single gas- detection monitor for all of the challenges mentioned above—one that utilizes photoacoustic infrared technology. Photoacoustic infrared technology is the newest method of gas detection. It enables gases to be detected at extremely low levels due to its inherent stability and reduced cross-sensitivity.
