Key Specifications
Full details →- Standard Range
- 0~50ppm
- Lower Detectable Limit
- <0.1ppm
- Zero Drift (24 hours)
- <±0.1ppm
- Response Time
- ≤60s
- Indication Error
- ±1%F.S
- SKU family
- CS-AIR-00008
An ambient carbon monoxide analyzer using gas filter correlation. The correlation wheel gives the instrument its own optical reference, so drift in the source or the detector cancels instead of appearing as concentration.
Key features
- Multi-tasking software allows viewing test variables while operating.
- Internal data logging with 1 min to 365 day.
- Temperature and pressure compensation.
- Continuous system diagnosis with alarm.
- Compliance with US EPA method.
Applications
Built for regulatory air-quality networks and urban monitoring programmes.
- ambient air quality monitoring
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 ambient carbon monoxide. It is built for regulatory air-quality networks and urban monitoring programmes. It is designed for continuous, unattended operation in a monitoring shelter or cabinet, with periodic zero and span calibration.
What measurement principle does it use?
Gas filter correlation. The correlation wheel gives the instrument its own optical reference, so drift in the source or the detector cancels instead of appearing as concentration.
Which specifications are confirmed?
The specification table lists five confirmed ordering parameters for this instrument. Use them to compare the operating range, utilities, and analytical performance required by the method. They include Standard Range at 0~50ppm, Lower Detectable Limit at <0.1ppm and Zero Drift (24 hours) at <±0.1ppm.
What should be confirmed before ordering?
Confirm siting and inlet configuration, zero and span gas supply, the calibration interval your reporting regime requires, and the data acquisition and reporting path. 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 and a multi-point dilution calibrator. Every concentration this analyser reports is measured against its zero. A zero that is not actually zero is a systematic error in every number downstream of it, so the calibration gear is not an accessory, it is what makes the readings defensible.
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.
