The J.U.M Model 3-700 FID is designed to be installed directly upstream of a FTIR analyzer to continuously measure the total concentration of hydrocarbons within a gaseous sample. All controls which allow to calibrate the FTIR or FID individually are built in. Sources can be ambient air, exhaust gases from a combustion process, stack emissions, from any type of an industrial vent, from an internal combustion engine, or from any other emission containing hydrocarbons. The Model 3-700 complements an FTIR analyzer with full THC monitoring capabilities.

QAL 1 (EN 14 181 and EN ISO 14956) and EN12619 regulations. They also fully complies with USEPA Method 25A and Method 503.It can be used as a table top instrument but is ideally suited to be integrated in CEMs.
