Non-contact, in-situ optical monitoring for demanding industrial processes.
PM Laser is a laser-based particulate monitoring solution designed for continuous, real-time measurement of dust concentration across industrial ducts, stacks, and pipes. Using a dual optical measurement approach, PM Laser delivers stable, accurate results with minimal maintenance, even in harsh operating environments.
• Enables continuous emissions monitoring to support regulatory and permit requirements
• High-resolution measurement down to <0.5 mg/Nm³ for applications with strict emission limits
• Reliable data output via 4–20 mA, Modbus TCP, and Ethernet for reporting and documentation
• Real-time dust concentration data helps operators optimize combustion, filtration, and material handling processes
• Dual-mode measurement ensures stable readings across changing process conditions
• Relay alarms provide immediate indication of high dust, warnings, or faults
• Minimal maintenance due to non-contact optical measurement
• Remote diagnostics and condition checks via Ethernet reduce site visits
• Long optical path options (MP, LP, XLP) allow correct sizing without mechanical compromises
• Handles high temperatures up to 700 °C (1292 °F)
• IP66-rated enclosure for harsh plant environments
• ATEX / IECEx Zone 2 approval available for hazardous areas
