Particulate Matter (PM10 / PM2.5) Sampler
Draws a known volume of ambient air through a size-selective inlet and a filter so that the mass of PM10 or PM2.5 particles collected can be weighed and expressed as µg/m³.

PREVENTIVE MAINTENANCE
Maintenance checklist
Each run
- Clean the inlet and check for insects or debris
- Check filter holder O-rings
- Check the logged flow and time
Weekly / fortnightly
- Clean and re-grease or replace the impactor surface
- Leak check
- Check the pump exhaust and dust filters
Monthly / quarterly
- Flow rate check against a calibrated transfer standard
- Temperature and pressure sensor checks
- Inspect pump brushes or vanes (blower motors)
Annual
- Multi-point flow calibration
- Transfer standard recertification
- Service of pump and flow controller
SAFETY
Safety precautions
Before you work on the PM sampler
- Use weather-proof electrical connections and earth leakage protection outdoors.
- Secure the sampler and stand against wind and tampering; use safe access for rooftop sites.
- Allow blower motors to cool before handling.
- Wear gloves when handling exposed filters, especially near industrial or toxic sources.
