The California Air Resources Board has released a comprehensive study where the performance of the Met One Instruments BAM-1020 configured to monitor PM2.5 is monitored at 18 sites throughout the state over a period of 1 year in the state’s multiple climatic regions. All BAM-1020 monitors were equipped with the smart heater. The results of this study unequivocally demonstrate the superior performance of the BAM-1020, previously shown in the US-EPA ETV program. The California Air Resources Board and associated air quality management districts currently deploy the BAM-1020 at more than 140 sites thoughout the state.
