Spectra-1 Multi Channel Gas Monitor

Spectra-1 Multi Channel gas monitor features the same gas analysis software as used by the open path Spectra-1 monitor. Tuneable Diode Laser Absorption Spectroscopy (TDLAS) based gas sensing. Remote laser transceivers with stainless steel enclosures are used for the individual open path monitors. A 19′ rack mounted central control unit is used with fiber optic and data cable interconnects to remote transceivers.
