CAC GAS Gas Flow Selector (GFS) series

The CAC GAS Gas Flow Selector (GFS) series for calibrating and testing gas detection instruments and gas analysers will allow two, four or six gas inputs to one gas outlet. A manual dial allows the user to select the gas required.

The GFS is a simple method of testing instruments with multiple sensors which require different calibration gas mixtures.

Versions for sample draw instruments and diffusion instruments are available. The diffusion version will have a flow meter on the outlet to adjust the flow rate.

The unit is housed in a 15 x 15 x 11 cm powder-coated steel enclosure, and all wetted materials are fully inert and corrosion resistant for use with reactive and corrosive gases.

The switch on the front rotates to different positions. Each position is labelled with the gas mixture and channel details. There are positions for incoming calibration gases and one is used for ambient air zeroing.

The GFS is suitable for service technicians who want a simple system to manually direct multiple gas mixtures to a single instrument.
