Fixed VOC Gas Detection 0 – 1000 ppm

The Falco fixed VOC Gas Detector, Diffused model, is an intrinsically safe and ATEX certified instrument making it approved for use in ATEX-zoned hazardous areas. Our fixed gas monitor is designed with Typhoon technology, making it able to withstand exceptionally harsh environments, including 0-100% relative humidity and condensing humidity, and temperatures from -40 to +50 °C without any compromise in performance.

In addition, the Diffusive model also has an externally located Intrinsically Safe sensor for quick and easy servicing without the need for a hot work permit and only requires annual maintenance. Dual certification allows your fixed VOC gas detector to be serviced and calibrated in a hazardous environment without having to remove power!

When you have the right gas detection system in place, your workers and site stay safe, and work continues smoothly.
