Volatile Organic Compounds Analyzer BTEX
VOC72e
Gas chromatography (GC) coupled with a PID detector. VOC monitor QAL1 certified to EN 14662-3, the newest standard for benzene measurement
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)
Quick check of the chromatograms possible directly on-screen, without the use of a computer
