A zero air generator supplying pollutant-free air for the zero-point calibration of ambient gas analyzers. Every concentration an analyzer reports is measured against its zero; a zero that is not actually zero is a systematic error in every number downstream of it.
Key features
- Dry, clean zero gas output with stable flow up to 20L/min and adjustable pressure.
- Designed for long-term, continuous, and reliable operation.
- Equipped with zero gas dew point and instrument fault alarms.
- Dual-stage dehumidification with automatic drainage minimizes maintenance.
Applications
Built for air-quality network operators and calibration laboratories.
- calibrating zero point of ambient air quality monitor

What does this instrument measure, and who is it for?
It measures nothing; it supplies the pollutant-free air that every analyser's zero point is measured against. It is built for air-quality network operators and calibration laboratories. It is designed for continuous, unattended operation alongside the analysers it feeds, in the same shelter or rack.
What measurement principle does it use?
Catalytic and adsorptive scrubbing of ambient air until every pollutant an analyser measures sits below that analyser's own detection limit. The output is not clean air in a general sense; it is air that is provably empty of the specific species being calibrated.
Which specifications are confirmed?
The manufacturer's published specification table lists three parameters for this instrument, and every one of them is reproduced on this page. They include Output at ≤20SLPM and Dew Point at ≤-20℃(≤10SLPM) ≤-10℃(≤20SLPM). ConductScience transcribed them from the manufacturer's engineering documentation without alteration.
What should be confirmed before ordering?
Confirm the total flow demanded by every analyser it will feed simultaneously, the outlet pressure those analysers expect, and the species that must be scrubbed below their detection limits. These are configured and quoted per installation, so raise anything unusual about the site during quote review rather than after delivery.
What else is needed to run it?
The ambient analysers it serves, and a multi-point dilution calibrator. A zero point alone establishes where the scale starts; multi-point calibration is what demonstrates the response is linear across it.
How is it supplied?
This instrument is configured and quoted per installation rather than sold at a list price. Request a quote and we will confirm the configuration, the site requirements and the lead time before anything is ordered.
