A continuous formaldehyde monitor reaching a 50 ppt detection limit in both air and liquid phase. Formaldehyde sits near the threshold where indoor-air and occupational limits are written, so the floor of the instrument sets the usefulness of the measurement.
Key features
- Low detection limit, ≤50 ppt.
- Adjustable time resolution: second-level or minute-level.
- Intuitive display of formaldehyde concentration trends over time.
- High-precision control of system modules (±0.1℃) ensures measurement accuracy.
- Unique flow path design for gas-liquid separation ensures real-time measurement.
Applications
Built for indoor-air quality, occupational hygiene and atmospheric research programmes.
- photochemical pollutants monitoring
- formaldehyde online monitoring

What does this instrument measure, and who is it for?
It measures formaldehyde in air and in the liquid phase. It is built for indoor-air quality, occupational hygiene and atmospheric research 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?
Continuous wet-chemical detection in both air and liquid phase. Formaldehyde sits near the threshold at which indoor-air and occupational limits are written, so the instrument's floor sets the usefulness of the measurement.
Which specifications are confirmed?
The manufacturer's published specification table lists seven parameters for this instrument, and every one of them is reproduced on this page. They include Minimum Detection Limit at ≤50 ppt, Accuracy at ≤±10% and Repeatability at RSD within ±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.
