In-Situ Multicomponent FTIR Gas Analyser Max. air consumption: 250 l/min for vortex cooling (cont.) 100 l/min for zero calibration/purge (15 minutes at 24 hour intervals) Gasmet FTIR In-Situ is industrial multicomponent gas analysers for continuous monitoring applications. The Gasmet In-Situ incorporates a Fourier transform infrared spectrometer, a sample cell which is directly inserted into the sample gas flow, and signal processing electronics. The analyser is fully equipped for fixed installations and it offers versatility and high performance for a wide range of applications. In-Situ analyser is equipped with a control box providing gas and electrical connections, and an external computer unit. The computer employs the same Calcmet user interface as an extractive Gasmet CEMS. The sample must be non-condensing and the upper limit for sample temperature is 250 oC. Sample cell absorption path length is 6.0 meters. Insertion depth of the sample probe is 736 mm and the flange diameter is 240 mm.
