Falco Diffused Gas Detector

Fixed VOC Gas Detector

The Falco fixed VOC Gas Detector, diffused model, is a fixed VOC gas detector that eliminates false readings found with other competing fixed detectors and continuously detects Volatile Organic Compounds (VOCs) in hazardous areas. The fixed VOC gas detector instrument is ideal for detecting VOCs in areas such as refineries and petrol chemical facilities.

Features

The Falco Diffused, fixed VOC gas detector has an externally located Intrinsically Safe sensor for quick and easy servicing without the need for a hot work permit. Dual certification allows your fixed VOC gas detector to be serviced and calibrated in a hazardous environment without having to remove power!

The standard Falco, both the Pumped and Diffused models are supplied with a 10.6 eV lamp allowing the fixed instrument to detect a wide range of VOC gases. The fixed gas detector has 4 detection ranges available, these ranges include 0 – 10 ppm, 0 – 50 ppm, 0 – 1000 ppm and 0 – 3000 ppm.

The fixed Falco TAC, both pumped TAC and diffused TAC models, utilise a 10.0 eV lamp to detect Total Aromatic Compounds (TACs) which help focus on benzene. The fixed Falco TAC is available with a detection range of 0 – 50 ppm.
