Air Quality Sensor Performance Evaluation Center

Evaluations - Criteria Pollutants

South Coast AQMD’s AQ-SPEC program aims at being the testing center for low cost air monitoring sensors to establish performance standards by which sensors are evaluated. The program evaluates sensors in the field, under ambient conditions, and in the laboratory under controlled environmental conditions. In the field, sensors are tested alongside one or more of South Coast AQMD’s existing air monitoring stations using traditional federal reference or equivalent method instruments to gauge overall performance. Sensors demonstrating acceptable performance in the field are then brought to the AQ-SPEC laboratory for more detailed testing in an environmental chamber under controlled conditions alongside traditional federal reference/equivalent method and/or best available technology instruments.
