The measuring principle is based on double pass technology which detects the difference between the transmitted and reflected frequencies and comparing them with a reference. The light beam sender/reflector arrangement, to measure particulate, stack or flue to reflector, which then returns the light to the sender where the intensity of the received light is measured. The light source is a green LED that will have the wavelength of 450nm to 600nm and transmits to the opposite multi angle reflector to reflect back to the sender. The display controller can be install at a maximum of 800 meters away to read and retransmit the data.
