Optical particle monitor for aerosol measurements
The ENVEA OPM250 is an optical aerosol spectrometer for ambient air monitoring. Equipped with the widest distribution range on the market, it provides real-time optical indication of even the smallest particles – PM1s.
Capable of measuring particles from 0.178μm to 29.4μm in any environmental conditions, the OPM250 is a versatile and dependable solution for air-quality monitoring. Operating at 1.2 L/min and measuring 100% of particles in real-time, the OPM250 has low power consumption and low running costs.
Precise particulate matter monitoring helps companies, governments and institutions reduce emissions, improve air quality and contributes to sustainability. The ENVEA OPM250 is QAL1 certified by TÜV for PM10 and PM2.5, and compliant with EN 16450. It also complies with EN 12341, EN 15267-1, EN 15267-2, and VDI 4202-3.
The OPM250 delivers a new standard in particulate matter (PM) monitoring. Unlocking more essential data than ever before, the OPM250 is a versatile and dependable analyzer that generates real-time results in all conditions.
Ambient air quality monitoring, industrial emissions monitoring and scientific environmental research.
The OPM250 is also suitable for particulate matter (PM) monitoring under any environmental conditions at all sites, including traffic, background, maritime, mountain, plus more.
