Which model for which need?
Start from your application
Not sure where to begin? Pick the description closest to your use case — it points you to the right gas mixer.
One span gas + one diluent
For routine multi-point calibration with only two gases, the compact Zephyr II is the most portable, plug-and-play choice — with an optional 6-hour battery for field work.
Choose ZEPHYR IIMulti-gas benches that grow
For 2 to 6 gases and needs that change over time, the fully configurable Aiolos III platform is the central gas blender for complex, multi-analyzer benches.
Choose AIOLOS IIIOn-site & mobile calibration
For AMS checks, audits and mobile labs, the Nomad brings the same traceable dilution technology to a rugged, portable case with a built-in PC.
Choose NOMADUp to 16 gases at once
For synthetic atmospheres, interference testing and chemometric model building, the Hurricane blends up to 16 gases simultaneously (up to 20 on request).
Choose HURRICANEHigh-throughput production benches
For continuous QA/QC and production environments, the GRack integrates GasMix™ technology into a 19″ rack for automated, always-on calibration workflows.
Choose GRACKVOCs, solvents & humidity
For compounds unstable or unavailable in cylinders, the Nephos generates gas standards directly from liquids using Coriolis mass metering — from % down to ppb.
Choose NEPHOSFAQ
Choosing a GasMix gas mixer
The most common questions when comparing the GasMix™ range.
How do I choose the right GasMix gas mixer?
Start from your application. For the simplest two-gas setup, choose the compact Zephyr II. For flexible multi-gas benches (2 to 6 channels), choose the Aiolos III. For field and on-site work, choose the portable Nomad. For complex mixtures of up to 16 gases, choose the Hurricane. For continuous industrial workflows, choose the rack-mounted GRack. To generate standards from liquids such as VOCs or humidity, choose the Nephos.
Which GasMix gas mixer has the most channels?
The Hurricane is the most powerful model in the range, blending 7 to 16 gases simultaneously, with custom builds up to 20 channels on request. The Aiolos III and GRack handle 2 to 6 channels, the Nomad 2 to 4, and the Zephyr II 2 channels.
Which GasMix model is best for on-site or field calibration?
The Nomad is designed for field use, packaged in a rugged case with a built-in PC. The Zephyr II is also field-ready thanks to its compact footprint and optional 6-hour battery. Both are ISO 6145-7 compliant and provide the same traceable metrology as benchtop GasMix systems.
Are all GasMix gas mixers ISO 6145-7 compliant?
Yes. The Zephyr II, Aiolos III, Nomad, Hurricane and GRack are ISO 6145-7 compliant, delivering ±1% setpoint accuracy and NIST-traceable calibration. The Nephos gas channels are ISO 6145-7 compliant, with liquid metering by Coriolis mass flow.
