What does this instrument measure, and who is it for?
It measures ambient particulate mass, rather than an optical proxy for it. It is built for regulatory air-quality networks and compliance 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?
Beta-ray attenuation across a collected deposit. It is a gravimetric-equivalent measurement, reporting mass rather than an optical proxy for it, which is what regulatory reporting requires.
Which specifications are confirmed?
The manufacturer's published specification table lists six parameters for this instrument, and every one of them is reproduced on this page. They include Resolution at 0.1μg/m³, Lower Detectable Limit at Reference Film Indication Error: ±0.5% and Reproducibility at Temperature Indication Error: ±0.5℃. ConductScience transcribed them from the manufacturer's engineering documentation without alteration.
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.
