GasMix GMRack - Rack Gas Mixer and Diluter

Using GasMix ™ GMRACK you benefit of :

• 19″ rack mounted industrial version of GasMix™
• On-board computer and a touch screen for easier control on site
• Up to 6 gas channels
• Can be remotely driven by Ethernet communication
• USB port on front panel to upload projects
• Compliance with ISO 6145-7

For easier use directly on site, the GMRack is equipped with on-board computer and a touch screen. Embedded GasMix™ software controls the mixer operation. It may drive an external injection valve and/or the Start command of an analyzer. The operator can do a single injection or run fully automated pre-programmed sequences for a linearity check or a multi-point calibration. A strong benefit of the GasMix™ is the drastic reduction of operator time.

GMRack is suitable for all types of instruments like gas chromatographs, microGC, gas analyzers, trace sulfur analyzer, FTIR, etc.
GMRack creates in situ controlled gas concentrations for analyzer validation, calibration or linearisation check.
