E Sampler smoke monitors

The contract involves the purchase of four air quality monitors specifically designed to measure particulate matter (PM 2.5) pollution during prescribed and wildfires. These monitors must be rugged, portable, and capable of operating on both 110v AC and 12v DC power sources to ensure reliable use in forest environments under various weather conditions. Additionally, the devices need to be compatible with the Oceaneering AQES-Muli satellite telemetry unit for data transmission. Performance-wise, the monitors must provide measurements that are reasonably accurate when compared to the Federal Reference Method monitors, aligning with EPA standards for air quality monitoring. This procurement supports compliance with the Clean Air Act as administered by the State of Arizona and assists in providing accurate smoke level data to the Arizona Department of Environmental Quality for public communication. The contract was issued by the Department of Agriculture's Southwest office, with the point of performance in Phoenix, Arizona. The focus on high precision and durability underscores the importance of reliable air quality data during wildfire events to meet regulatory and public health requirements.
