System Concept
ZEPHYR brings on‑site customized gas standard preparation to a compact footprint. Thanks to its embedded ZeSoft and 5″ touch interface, Zephyr can be installed exactly where you need it: on a bench, in a mobile lab or next to the analyzer. It is widely used for applications that involve only two gases, such as multi‑point calibration from a concentrated standard plus diluent.
The interface is intuitive and fully automated: run a single injection or a pre‑programmed sequence. ZeSoft computes the target flows, calculates uncertainty of the final concentration (considering MFC flows and parent gas certificate) and logs events for traceability.
Smart Sequence Builder creates multi‑point curves in one click — choose number of points, start/stop concentrations, and the software generates the levels automatically. Optional battery guarantees up to 8 hours of uninterrupted operation in the field or during mains cut‑off.
Operation & Software
ZEPHYR is operated via the built‑in ZeSoft on a 5″ touch screen — no PC required. It can also exchange signals with an analyzer via dry contact or TTL. Projects store gas libraries, MFC calibration curves per gas, user settings and analyzer sync parameters.
- Touch‑first UI with embedded control — plug & mix
- Smart Sequence builder for multi‑point recipes
- Automatic uncertainty calculation and reporting
- Compatible with aggressive/reactive gases
- Battery option for 8 h autonomous operation
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.
- ISO 6145‑7 compliant
- NIST‑traceable calibration
- Uncertainty calculation
- ±1% set point accuracy and <0.1% repeatability *
- Dilution factor: 2,000 in standard - up to 10,000
- Analyzer sync via dry contact/TTL
