APPARATUS FOR DETERMINING ODOR LEVELS IN GAS STREAMS

摘要

A microprocessor-based apparatus is provided for determining oder levels in gas streams. The apparatus includes a mixing chamber (60) for mixing gas from a gas supply to be tested with air to form a gas-ai r mixture. The gas is received through a gas inlet port (50). Air is received through an intake port (48). The gas air mixture exits the mixing chamber via an outlet port (58). A motorized fan (94) is positioned in a conduit (76) connected to an outlet port of the mixing chamb er for drawing the gas-air mixture out of the mixing chamber to a location where it can be sniffed by the user to detect oder. The apparatus also includes a microprocessor controller (100) and can be linked to a personal computer (108) to enable data to be exchanged between t he personal computer and the apparatus.
