Airborne particle monitoring measures the number and size of particles at a single point. This is done either with a particle counter, or by collecting the airborne particles on a filter or a deposition surface so that the collected particles can be characterized by microscopic observation. The particle counter is usually an optical particle counter or a condensation nucleus counter. Particulate sampling involves determining the number and size of particles in a specific volume of air. The sample volume of air is pumped through a capillary sensing chamber where a beam of light illuminates an individual particle. Measurements of light scattered off the particle provides information on the optical size of the particle. The numbers and sizes of particles are collected and stored in the instrument memory. Results are displayed in terms of particles per unit volume of air in selected size ranges.
Airbox Flanges helps to secure the duct to the air box in a cold air kit. A cold air kit comes with air box flange, flange template, duct, inlet port, hose clamps and fasteners. The cool power air intake system provides additional cold air to the stock sealed air box through a PSM duct located beneath the air box. Cold air is picked up as the air passes under the vehicle. Air enters an inlet port located behind the bumper at the bottom of the stock vertical air baffle.
