GASMIX™ PORTABLE
Gas Mixer and Gas Diluter for On-Site Field Calibration - NOMAD
Field-ready GasMix™ mixer/diluter — portable calibrations for analyzers
Built‑in industrial PC & touch — GasMix™ Windows software, projects, sequences, Audit Trail.
System Concept
NOMAD brings the popular GasMix™ dynamic mixing and dilution technology to the field — for auditors, QA engineers, CEM operators, air monitoring stations and mobile labs. Packaged in a rugged case with a built‑in industrial PC and large touch screen in option, it enables on‑site calibrations and verification of gas analyzers wherever you need them.
Standard gases, sequences and projects are created and stored directly in the GasMix™ software: library of gas standards, multi‑point MFC calibration tables, user profiles, analyzer control parameters and more. NOMAD is compliant with ISO 6145‑7 and provides the same rigorous metrology and traceability as benchtop GasMix systems.
A typical configuration with 4 channels connects two span gases, one interference gas and one dilution gas — delivering full multi‑point span & zero calibrations, linearity and repeatability checks, purity/interference tests and custom sequences.
Operation & Software
NOMAD is operated from its integrated touch PC or an external computer via Ethernet. The GasMix™ application calculates dilution/mixture flows from target concentrations using stored calibration tables, runs user‑programmed sequences, and synchronizes with external analyzers for manual start or fully automatic cycles.
Project‑based workflows
User‑programmed calibration sequences (span/zero, linearity)
Handles pure,concentratedn aggressives gases
Audit Trail
Remote supervision via Ethernet; Windows environment
Metrological Excellence
Every integrated Mass Flow Controller (MFC) undergoes 400‑point factory calibration across the full dynamic range and for each selected gas matrix (He, Ar, CH4, H2, N2, Air, …). This ensures superior linearity and precision, especially at very low and very high flow rates.
NIST-traceable calibration
±1% set point accuracy and <0.1% repeatability *
Automatic K-factor calculation & correction
Automatic uncertainty calculation, full QA/QC traceability with Audit Trail
Certificate delivrance with concentrations & uncertainties
* Valid when all MFCs operate between 10% and 100% of full‑scale flow.
