Overview
The Fine Particulate PM2.5 Sampler from  is built for accurate, repeatable field sampling of respirable and coarse airborne particles. Engineered for regulators, research labs, industrial monitoring, and environmental consultants, this sampler combines USEPA-conformant size-selective inlets with a stable, low-noise vacuum pump and a rugged outdoor housing — delivering dependable performance in long-term ambient monitoring campaigns and spot checks alike.

Why this sampler?
If you need reliable PM2.5 (and PM10/TSP where required) mass collection with straightforward operation and low maintenance, this unit is designed for the job. It balances precision flow control, field-friendly ergonomics, and transportable form factor so teams can deploy quickly and collect defensible data even in challenging sites.

Key Features

• Size-selective inlets: Includes PM10 impactor and WINS impactor configured for PM2.5 sampling — designed to conform to USEPA inlet specifications for accurate particle cut-points.
• Stable sample flow control: Flow control and reporting via an integrated rota meter to maintain the required volumetric flow throughout the sampling period.
• Elapsed time & totalizer: Built-in elapsed time indicator and time totalizer to track sample duration and runtime for easy record keeping.
• Leak check testing: Leak check adaptor provided for on-site verification of system integrity before and during sampling.
• Quiet, maintenance-friendly pump: Low-noise diaphragm vacuum pump with AC motor and brushless (non-carbon brush) design — non-pulsating flow with reduced maintenance and longer service life.
• Standard filter media: Filter holder accepts standard 47 mm filters for easy sourcing and laboratory processing.
• Robust outdoor enclosure: Powder-coated metallic housing engineered for outdoor field use and protection from the elements.
• Transportable mounting: Overall sampler height is 1.75 m (ground to top of sampling inlet) with supplied tripod stand for stable field mounting.
• Flexible power options: Nominal 220 V, single-phase, 50 Hz mains supply. 110 V, 60 Hz option available on request for alternate regions.
