Abstract
A system and method for simultaneously running a plurality of air quality sensor units using a centralized station and software to test for field performance upon factory return from field installations, automatically identify preventative maintenance requirements, and automatically calibrate the sensor units and generate quality metric reporting. The centralized station and software include a computer, a manifold, tubes, and cables. A test gas is supplied, wherein the manifold distributes the test gas. Once powered and supplied with test gas, the sensor units are tested simultaneously. The computer runs software that compares the test data collected from the sensor units to determine if any of the sensor units fail standards or produce data that deviates from a mean average range. Sensor units that do not require maintenance are calibrated using test gasses to generate calibration coefficients which are stored within the sensors' firmware.
