The GFM 406 is an instrument designed for a variety of applications. It is fully configurable to each client’s requirements, making it a uniquely versatile instrument. Gas Data’s software and hardware present clients with a wide range of gas analysis options.

This instrument provides pressure measurements across three reference points: Atmospheric; Static (Gauge); Differential. The velocity of the gas within a pipe can be captured using an optional vane anemometer.

It can be configured with infra-red channels for ch4 and co2 analysis – with an optional LEL expansion – alongside up to four electro-chemical cells to measure any combination of O2, CO, H2S, H2, or hydrocarbons.
