Products, Gas and Dust Monitors
In the early nineties we started to develop gas monitors based on tuneable diode lases (TDL). The first commercial TDL gas monitor was introduced on the market in 1995 using the trademark LaserGas. The LaserGas monitors are also based on single line spectroscopy and measure in-situ. LaserGas monitors for measurement in stacks or in open paths up to several hundred meters are available.
A range of dust monitors based on laser technology has also been developed and can be used in stacks or in open paths.
LaserGasThe current version, LaserGas II, is available in 4 different configurations and for several gases. The configurations are:

LaserDustThe LaserDust monitor developed by Norsk Elektro Optikk is designed for use in stacks and other cross-duct applications. Typical applications are emission monitoring in dry scrubbers in aluminium smelters, in waste incinerators and power plants. This dust monitors could be used as a tool for optimising scrubbers and filters as well as broken bag detection in bag house filters.
Main features of the LaserDust are:
The LaserDust Monitor is based on a combination of forward scatter and transmission measurement of the laser light which makes it possible to cover a high dynamic range. Lower and mid-level dust concentrations will be measured using the forward scatter technique while the higher dust concentrations will be based on transmission measurements i.e., a high sensitivity can therefore be combined with a high dynamic range.
