Laser air pollution sensor Dienmern SB4674 — 8-in-1 particulate monitor for PM10, PM2.5, PM1.0

Dienmern SB4674 is a laser-based 8-in-1 air pollution sensor designed to detect and measure particulate matter concentrations, specifically PM10, PM2.5 and PM1.0. The compact detector provides continuous monitoring of airborne particles and calculates real-time concentration values to support air quality assessment. Its laser scattering measurement principle delivers stable readings suitable for indoor installations, integration with HVAC systems, environmental monitoring stations and portable monitoring devices.

Advantages

The sensor combines multi-channel particulate detection with a compact form factor to enable continuous, accurate monitoring in constrained spaces. Laser-scattering detection ensures sensitivity to a range of particle sizes while providing rapid response to changes in concentration levels. The device is engineered for integration: it supports data output compatible with common monitoring setups and can be deployed in both fixed and mobile configurations. Low maintenance and steady sampling help maintain reliable results over prolonged operation.

Suitable for

• Indoor air quality monitoring in offices, homes and public buildings
• HVAC system integration and ventilation performance checks
• Environmental monitoring stations and urban air quality networks
• Mobile or portable devices for personal exposure assessment
• Research and development projects requiring particulate concentration data

Key specifications

• Measurement principle: laser scattering particle detection
• Measured fractions: PM10, PM2.5, PM1.0 (multi-channel)
• Form factor: compact, designed for fixed or mobile installation
• Output: continuous real-time concentration data suitable for integration
• Performance: rapid response to concentration changes with stable baseline readings

How to use

Install the sensor in a representative location for the space or device where particle concentrations need monitoring, avoiding direct airflow obstructions and sources of vibration. Connect the unit to the monitoring or control system according to the integration interface provided by the host equipment. Allow an initial warm-up period for the laser to stabilise before relying on quantitative readings. Periodically verify readings against a calibrated reference if high-accuracy validation is required, and follow standard procedures for placement height and sampling orientation to obtain consistent results.

Usage recommendations

For reliable long-term performance, place the sensor away from direct combustion sources and large dust generation points, maintain a regular inspection schedule to remove surface dust, and follow the manufacturer's guidance for environmental operating ranges. When integrating with HVAC or monitoring networks, confirm data format compatibility and plan for periodic validation to ensure measurement traceability.
