dust-monitor-050715-body.jpgAmetek Land has launched the 4650-PM Continuous Dust Monitor. The company says the technology has been used in Europe and can help U.S. power plants to meet the EPA’s new Mercury and Air Toxics Standards (MATS) for particulate matter measurement.

The U.S. Environmental Protection Agency’s (EPA) new MATS rules sets particulate matter (PM) limits for coal and oil-fired EGUs (Electricity Generating Units). The 4650-PM is suitable for both PM-CEMS (PM-Continuous Emission Monitoring) and PM-CPMS (PM-Continuous Parametric Monitoring System) in dry stacks where condensed water is not present.

The monitor has a minimum range of 0-15 mg/m3, which allows it to fully meet the requirements of the MATS rule. The design of 4650-PM is based on QAL1 certified, highly accurate forward-scattering laser technology that has been proven to be highly effective at measuring PM in Europe since 2009. Patented technology incorporated into 4650-PM is therefore capable of exceeding all American Society for Testing and Materials (ASTM) and U.S. Environmental Protection Agency (EPA) requirements. Its large-area collection optics and stable optical design allow it to achieve a detection limit < 0.1 mg/m3.
4650-PM, which is made in the UK, offers variable insertion depth and has no continuously moving parts for excellent reliability. It is able to operate in a wide range of stack temperatures up to 480 °F as standard (higher temperature options available on request). Advances in connectivity means that is it compatible with TCP-IP Ethernet, RS485, 4-20 mA outputs and is supplied with multiple display modes and a large graphics screen with intuitive menus.
