The PM2.5 Fine Particulate Sampler APM 555R is a professional air monitoring instrument designed for accurate measurement of fine dust particles in outdoor and industrial environments. It uses USEPA-standard PM10 and WINS impactors to ensure reliable PM2.5 sampling, making it ideal for pollution control boards, environmental labs, and industrial safety teams.

Built with a low-noise vacuum pump, stable flow control, and 47 mm filter compatibility, this sampler delivers consistent results even during long sampling cycles. Its weather-proof powder-coated enclosure and 1.75 m tripod setup make it perfect for continuous outdoor monitoring.

If you need regulatory-grade PM2.5 data, this is the tool — not a toy, not a demo unit, a real field instrument.

This High Volume Air Sampler is designed for accurate and reliable ambient air monitoring in field and industrial conditions. It measures air flow directly in m³/min, ensuring correct and consistent sampling results.

The sampler can collect fine particulate matter down to 1.6 microns and also supports gaseous pollutant monitoring with an optional attachment. A 24-hour programmable timer allows automatic sampling without constant supervision.

Its brushless blower ensures low noise, long life, and zero carbon brush replacement. The rugged, compact body with a separate gable roof makes it easy to transport and suitable for harsh outdoor use.

Ideal for pollution control boards, environmental labs, and industrial air quality monitoring.

APM560 (DFC) Respirable Dust Sampler is designed for accurate monitoring of respirable dust in industrial and environmental applications. It ensures stable flow control and reliable particulate sampling even under heavy dust load conditions.
