A dynamic dilution calibrator using two mass flow controllers to generate zero and multi-point span standards from a single cylinder. Multi-point calibration is what distinguishes a demonstrated linear response from an assumed one.
Key features
- Mercury lamp intensity attenuation alarm ensures ozone concentration accuracy.
- High-precision mass flow controller supports sample gas ratios up to 12,000.
- Easy-to-use calibration programming for personalized calibration needs.
- Stable operation with high precision, repeatability, and simple operation.
Applications
Built for air-quality network operators and calibration laboratories.
- standard zero and span calibration of ambient air quality analyzers
Choosing the right configuration
Specify the target species, measurement range, zero and span equipment, sample conditioning, shelter or rack arrangement, communications, and reporting method as one monitoring system. ConductScience reviews the site and calibration plan before quoting.

What does this instrument measure, and who is it for?
It measures nothing; it generates the zero and span standards an analyser is calibrated against. It is built for air-quality network operators and calibration laboratories. It is designed to sit in the rack with the analysers it calibrates, driven on a schedule set by the reporting regime.
What measurement principle does it use?
Two mass flow controllers blend a certified span gas with zero air, generating a series of known concentrations rather than a single one.
Which specifications are confirmed?
The specification table lists nine confirmed ordering parameters for this instrument. Use them to compare the operating range, utilities, and analytical performance required by the method. They include Diluent Gas Flow Range at 0-10 SLPM (expandable), Flow Linearity at < ±1% F.S. (within 20%-80% of full scale) and Source Gas Flow Range at 0-100 sccm (expandable).
What should be confirmed before ordering?
Confirm the certified span-gas cylinders and concentrations you will dilute, the diluent supply feeding it, and the number of calibration points your reporting regime requires. 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?
A zero air generator to supply the diluent, a certified span gas, and the ambient analysers being calibrated. Multi-point calibration is what distinguishes a demonstrated linear response from an assumed one.
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.
