CAC-GFS: Gas Flow Selector

The GFS – Gas Flow Selector has been designed to provide a solution for manually calibrating instruments with multiple sensors. A simple turn of the dial allows calibration gas to be selected and delivered to a single instrument. Housed in a 15cm x 15cm x 11cm powder coated steel enclosure, and all wetted materials are fully inert & corrosion resistant for use with reactive & corrosive gases.

Different versions are available for 2-6 gas inputs for either pumped or diffusion instruments using either non-refillable cylinders or large volume high pressure cylinders.

The switch on the front rotates to different positions. Each of the location indicates which gas/channel is selected. There are positions for calibration gases, zeroing and an off position (diffusion versions).
