Continuous optical extractive dust measurement technology - learn more at CEM 2025

The OPM 19 ED from Dr. Foedisch delivers advanced continuous, optical extractive measurement of dust content in wet and sticky exhaust gases. This highly advanced instrumentensures precision monitoring even in challenging industrial environments. It operates within an ambient temperature range of -20 to +50 °C and withstands relative humidity up to 90% (non-condensing). Its compact design requires minimal installation space with a single sample flange, integrated or separated return fitting, and optional flow measurement for isokinetic setting. The device provides real-time dust content analysis using optical scattered light technology, with results displayed in mg/m³ via input calibration parameters. Integrated isokinetic gas sampling ensures representative dust concentration measurements, enhancing precision and reliability. The system is operable via PC software or an optional display/operating device for seamless data visualisation and control.

The OPM 19 ED samples exhaust gas through a temperature-controlled probe, which conveys the gas to a measuring cell. The gas is continuously diluted and dried using heated, dust-free ambient air. Optical scattered light technology detects dust particles, and the electronic processing unit converts the signal into an equivalent dust concentration measurement. This highly efficient monitoring solution is ideal for industrial applications where wet and sticky exhaust gases pose a formidable challenge to conventional dust measurement techniques. The OPM 19 ED provides reliable continuous monitoring for process optimisation and regulatory compliance. Its compact design reduces installation complexity and maintenance requirements, while enhanced accuracy is achieved through isokinetic gas sampling and real-time data analysis. With its robust design and cutting-edge measurement technology, the OPM 19 ED delivers the ideal solution for dust content monitoring in demanding industrial environments.
