Unisearch LasIRTM Gas Analyzer is a continuous monitor designed to measure flue gases for both compliance and process monitoring. The Controller uses a near infrared (NIR) Tunable Diode Laser Absorption Spectrometer System utilizing a single mode laser mounted in a thermoelectric cooler for unsurpassed accuracy and performance. Since the spectral purity of the laser is high
and the selected absorption feature is unique, measurements can be made free of interferences from any other gas. The measurements are made either in‐situ across the stack or duct in either a single or dual pass design (depending upon the application), open-path or extractive by sampling and flowing the gas through a gas cell. A Windows based software package displays the data on either a Host laptop PC or the client’s existing data acquisition system.
