Spectra-1 Extractive Gas Monitor


Spectra-1 Extractive 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. Closed path internal multi-pass sampling cells are used instead of an open path configuration to calculate gas concentrations. 19′ rack mounted design. Options include internal sampling pump and 4-20mA output. Standard configurable RS232 data output.
