Timed Filter Sampler
The filter sample unit consists of a diaphragm pump and a timer. The air mover is a linear pump with a maximum sample flow rate of 17 LPM . The outflow from the pump can be connected to a dry gas meter to measure volume sampled.
Dry Gas Meter
The dry gas meter (DTM) is a primary standard for measuring air volume. The AEM Volumetric gas meter, with diaphragm, meets requirements of the International Legal Metrology Organization (OIML) and EN-1359-1998. MAX Flow rate = 2.5 m3/hr (41 LPM), Min flow = .016 m3/hr (0.26 LPM), Min Pressure 0.5 bar, limit error ( Qmin
Standard Smoking Machine Hood
The hood area is 30x24x21 inches (76x61x53 cm) with filter in area back of the TE-10 smoking machine. The errant smoke is captured from the smoking machine to keep exposure area free of smoke. Below the TE-10 unit is the mixing and dilution (m&d) chamber which collects the side-stream and mainstream smoke from the TE-10 …
Small Hood
The small hood is 24 x 20 x 19 inches (61x51x48 cm) and is used with the TE-2 manual smoking machine. A high-pressure. high-volume fan provides suction from the back through a filter that exits through a 3-inch duct to the external ductwork. Extra-capacity exhaust provides the flexibility to add other exposure chambers or for …
Cage Insert
The “cage insert” is an aerosol delivery unit designed to be placed into a standard polycarbonate cage for animal exposures. The aerosol is introduced into the cyclone-type top and distributed through a fine, mesh, perforated screen. Aerosol distributions of aerodynamic diameters with a mean diameter of 3 micrometers have been tested for distribution and found …
