UNISEARCH ASSOCIATES INC-LasIR INSTRUMENTS

LasIR gas measurement instruments are based on the absorption of light in the infrared region of the spectrum. Their unique light source is a tunable diode laser – a tiny solid state device, the laser emission wavelength of which depends on the composition of the lasing chip, the temperature and the current passing through the chip. The standard LasIR employs lasers in the red to Near Infrared region (700 – 2700 nm) which are similar to those found in consumer products such as CD players, but the laser wavelength can be tuned to the gas absorption feature of choice. The light emitted from these lasers can be fiber-coupled, allowing the analyzer electronics to be located hundreds of meters from the actual measurement point. This is an important feature for measurement locations that are not easy to access or are in hazardous locations. It is also possible to multiplex the laser to multiple locations (up to 16 as standard), allowing measurement of the gas at multiple locations with a single analyzer. This makes the system very cost effective. The same system can be used for in-situ and/or extractive gas measurements in any combinations.

LasIR RP – Mini Portable Series

• An analyzer and optic assembly designed for applications that require ambient air measurements – potrooms, remote paths, and mobile applications.

LasIR RS – Mini Stack Series

• An analyzer with built in optics designed for durability, for in situ, real time stack and duct measurements. Enclosure may vary in size.

LasIR RD and RR(B or M) – Standard Series

• Standard series analyzers are designed to send and receive signals from a central control room to various measurement points. The analyzers come in two sizes; table top (RD) available for 1-2 locations and 3U rack mounted versions (RR) capable of measuring up to 16 locations using a single analyzer. Two configurations are available for the rack mounted (RR) analyzers to select the measurement location; the RR (B)- Series which employ beam splitters (2-8 locations) and the RR (M)-Se- ries which employs optical multieplexers (2-16 locations). Use of beam splitters or optical multiplexers is determined by the dust loading in the measurement path.
