LasIR 低价位高可靠性TDLAS 激光气体探测仪

UNISEARCH ASSOCIATES is the only company that offers all three spectroscopic methods for monitoring gases for environmental, continuous emission and process control applications. Spectroscopic methods provide the best method for identifying and quantifying a variety of gases with a minimum of interferences from other gases and particles.The LasIR, based on our TDLAS technology, is the method of choice where sensitivity, freedom from interference and fast response time is required. It can measure a se-lected number of important gases at parts per billion concentrations in times less than one second. The systems are modular and are available for (1) fence-line, perimeter and fugitive emissions, (2) for stack and duct monitoring, and (3) for point and extractive measurements. For further information about the LasIR systems please click here.FTIR (Fourier Transform Infrared) systems are preferred when a larger list of known or unknown gases need to be measured simultaneously. Up to 200 gases can be measured at the same time. It is particularly suited to measurements of hydrocarbons and organic gases. Systems are available for (1) extractive process or stack monitoring (2) open path systems for fence-line monitoring and (mobile laboratories for ambient air monitoring.

The system is configured for long path measurements suitable for fence-line/perimeter, fugitive and ambient air monitoring. The system was licenced by UNISEARCH ASSOCIATES to Thermo Environmental Instruments who manufacture and market the instrument. For further information on the DOAS system please consult the web site: http://www.thermoei.com/opm.htmIn addition to the spectroscopic instruments, UNISEARCH ASSOCIATES offer a line of lightweight, battery-operated, highly sensitive instruments based on a novel surface chemiluminescence process. These LUMINOx instruments are available for measurement of O3, NO, NO2, NOx, and PAN. They combine high sensitivity with fast response time and their ready portability makes them ideal for indoor, remote area and aircraft operations as well as for general monitoring.
