Benzene Fenceline Monitoring

 The MAX300-AIR can measure fugitive benzene at < 0.6 µg/m3 (0.2 ppb).  Recent amendments to 40 CFR 60 and 63 have lowered the actionable level to 9.0 µg/m3 (2.8 ppb),  at this concentration Extrel mass spectrometers offer a real-time, fully automated solution with better than 99.9% accuracy.  

Air is pulled continuously from the sample points back to the MAX300 for analysis. There is no need for personnel to manually collect samples, or send anything to an offsite lab, and real-time alerts of benzene transients are crucial for easily and accurately identifying the source.

For over 45 years Extrel has provided the very best support to industry for their environmental and emissions applications.
