Unisearch LasIR^TM Gas Analyzer is a continuous monitor designed to measure open path both compliance 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. A Windows based software package displays the data on either a Host laptop PC or the client’s existing data acquisition system.

Power Meter

The fiber/coax power meter is employed to measure both, the laser power transmitted through the fiber optic cable (for fiber optic cable verification) and the return signal as seen directly by the IR detector (for optimizing alignment). The meter is required for measurements at specific wavelengths. The meter is an essential tool for checking system components and should remain on site with the equipment.
