Falco TAC Pumped - Fixed Gas Monitor

Falco TAC Pumped

Fixed Gas Monitor

The Falco TAC pumped is a fixed gas monitor that eliminates false readings found with other fixed has monitors and continuously monitors Volatile Organic Compounds (VOCs) in hazardous areas. The Falco TAC pumped, fixed gas monitor uses a sample line to draw samples and is ideal for use in difficult locations such as underground or in confined spaces.

Fixed Gas Monitor – Features

Falco, our fixed gas monitor, 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 gas monitor to be serviced and calibrated in a hazardous environment without having to remove power!

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

The Falco TAC, both Pumped TAC and Diffused TAC models, utilise a 10.0 eV lamp to monitor Total Aromatic Compounds (TACs) which help focus on benzene. The Falco TAC is available with a monitoring range of 0 – 50 ppm.
