Teledyne API, a business unit of Teledyne Technologies Incorporated (NYSE:TDY), announced today a new ambient air quality monitoring instrument, the Model T640 PM Mass Monitor, that measures the concentration of fine particulate matter below 2.5 microns in diameter (PM2.5) continuously, in real-time. Fine airborne particles are known to be hazardous to human health and are one of the main causes of reduced visibility or haze in many parts of the United States and elsewhere in the world. PM2.5 is an important measure of particulate pollution that is regulated by the U.S. Environmental Protection Agency (EPA) and by equivalent government agencies around the world. Teledyne API's T640 instrument has achieved regulatory approval from the U.S. EPA, and Teledyne is actively pursuing a number of international certifications, including for growing markets in China and India, where public awareness of poor air quality continues to gain attention. Teledyne API particulate monitoring instruments have been rapidly adopted by air quality monitoring agencies across the United States and in a growing number of countries across the world, with several hundred units already in operation. "We expect this momentum to accelerate based on the incredible rate of adoption we have seen in the U.S. EPA national monitoring network, and as the instrument receives the required international regulatory approvals," said Martin Abbott, General Manager of Teledyne API. "This new instrument serves the growing market need to produce more accurate, time-resolved PM2.5 measurements, with very low operating and maintenance costs."
