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 both controlled laboratory conditions and in the field. Ideally two triplicate sets of VOC sensors from the same production and quality control (QC) batch will be tested simultaneously in the field and laboratory. If only one triplicate can be obtained, the sensors will first be evaluated in the laboratory under known controlled conditions and concentrations of VOC concentrations, and then proceed to field evaluation if they demonstrate acceptable performance to warrant further evaluation efforts.
