is a device designed to collect online data in tunnels and provide it to the traffic monitoring department to provide reliable basis for tunnel ventilation and road traffic. The analyzer consists of a transmitter/receiver unit and a reflection unit. The installation distance is meters or meters, and the total optical path after reflection is meters or meters. The light beam is attenuated by the dust, and the signal is obtained and processed into a measured value by the evaluation unit. The analyzer automatically compensates for the effects of contamination and long-term drift. The negative gas absorption correlation method is used to measure the concentration at the absorption peak of the undetermined infrared absorption spectrum wavelength .. micron.
R The detector is not affected by environmental interference light and has self-test and automatic calibration functions.
