Pm2.5 Fine Perticulate Sampler

Fine particulate Sampler

Application:

The fine particle sampler is a compact and powerful PM 2.5 monitoring tool in ambient air and is designed for users who frequently move the device from one place to another.

Working Principle:

The effects of PM10 and PM2.5.5 used in microscopic samples are based on standard USEPA designs, so the system complies with international standards for PM2.5 transit. Ambient air enters the fine particle sampler through a multi-directional inlet designed to provide a clear aerodynamic cutting point for particles greater than 10 microns. The wind stream is undergoing a victory effect that keeps the fracture between PM10 and PM2.5. The sampling rate is kept constant at 1 m 3 / hour for the critical aperture. A special, lightweight, oil-free pump is used in the device and sufficient cooling air is provided to ensure that the operating temperature near the filter holder remains close to room temperature. The sample rate is continuously displayed on a basic rotary scale, while the sample duration is provided by the time collector.

Features:

• PM 10 and PM 2.5 Impactors as per designs standardized by USEPA.

• Brushless, Oil-free, light weight pump practically requires no maintenance.

• Filter holder designed for any 47mm diameter filter media.

• Provision to attach gaseous sampler.

• Compact cabinet design for easy portability

Specification:

• Flow Rate : 1 m3 /hr controlled by Critical Orifice and displayed on a rotameter requires no maintenance.

• Size Selective Inlets : PM10 Impactor and WINS Impactor for PM2.5 conforms to USEPA design.

• Vacuum Pump ; Oil Free, light weight pump driven by brushless induction motor.

• Time Totalizer : Records the actual time duration of each sample.

• Provision to attach Gaseous Sampler : The APM 550MINI has an in-built valve and piping for use of agaseous sampling attachment for monitoring SO2, NOx, NH3, Ozone etc.

• Compact & Light ; Single unit compact cabinet made of Aluminum is light and robust.

• Calibration Unit : Leak Check & Flow rate measurement adapter
