4000VM Gas Analyzer
Chemiluminescence NOx

Model 540
Sample line controller


destruction efficiency

Destruction Efficiency

These systems are custom designed to specification for monitoring VOC destruction or removal efficiency across thermal ozidizer, catalyst bet, carbon bed or bio-filtration units. Measurement is made using a pair of heated total hydrocarbon FIDs. Calculations, data archiving and reporting are performed in our fully-featured and user-configurable DAS.
