VOC72M Volatile Organic Compounds Analyzer BTEX

SKU: VOC72M

Volatile Organic Compounds Analyzer Btex 2 | ENV Monitoring

The VOC72M’s metrology, in accordance with EN 14662-3 (2005) & EN 15267-1 (2009) standard for benzene measurement, is based on gas chromatography (GC) coupled with a photo-ionization detector (PID).

Compact and fully automated analyser providing equal performance to the laboratory chromatographs; particularly well-suited for fixed or mobile ambient air quality monitoring stations.
• Standard measured compounds: Benzene, Toluene, Ethylbenzene, m+p-Xylene, o-Xylene, 1-3 Butadiene (other compounds on request)
