A new continuous particulate emissions monitor and baghouse filter leak analyzer incorporates automatic self-checks (zero and span) to ASTM standards to automate compliance with regulatory requirements for periodic instrument validation. The particulate monitor also features system checks to simplify installation and setup and to improve overall performance. Benefits include stack monitoring, detecting filter leaks, eliminating cleanup costs, preventing the escape of valuable powders, and protecting downstream equipment such as blowers and HEPA filters.
