- corrosive gases
- Line measurement, integral concentration over the full stack diameter
- Suitable for harsh environment
- Low Maintenance
Principle
The laser gas monitors operate on the principle of “infrared absorption line spectroscopy,” which is based on the fact that most gas molecules absorb light at a specific wavelength. The monitor conducts measurements using the correlation between the amount of laser light absorbed by the molecules of the object gas and the concentration of the gas.
A technique called “laser wavelength modulation” is used in the monitor in order to increase the detection sensitivity of the receiver unit.

Example of equipment configuration (LaserGas II SP).
The laser gas monitors consist of a transmitter embedded with a semiconductor laser unit and an optical receiver unit that incorporates a photodetector. The transmitter and the optical receiver
both have purge unit/optical-axis alignment functions. In addition, the LC display panel of the light sensor displays the gas concentration, laser transmission rate, and error messages (at the time of error).
Gas type applications.
