Fixed detectors are used to detect an abnormal or dangerous presence of gas in a specific area and to warn the user in the event of potential hazards. Equipped with sensors (called cells), they can measure the concentration of one or more types of gas, depending on the model.
Unlike portable detectors, fixed detection devices make it possible to secure an entire area 24 hours a day. They can also be connected to a detection system, which displays the gas concentration in numerical value, and then triggers the servo-controls in the event of an abnormal value.
