TEST CHAMBER FOR EMITTING POLLUTANTS WITH AIR SUPPLY PIPE

摘要

A test chamber for emitting pollutants with an air supply pipe is provided to remarkably shorten the time for measuring the density of the pollutants by increasing the emission speed of the pollutants. A test chamber for emitting pollutants with an air supply pipe includes a lid section(210), an air supply pipe(215), and a body section(230). The lid section includes an air supply channel and an air discharge channel. The air supply pie is communicated with one end of the air supply channel to supply air into the interior of the test chamber. An opened end of the body section is installed so as to close the lid section. The flow area is adjustable by regulating the separation distance between the air supply pipe and the test material and the flow quantity of the air supplied from the air supply pipe.
