Measuring principle

Using the principle of transparency ratio, the transmitter head and the reflector are installed opposite to each other. Using the principle of automatic alignment, the test light passes through the test channel. The light emitted by the transmitter head passes through the test channel for the first time, is transmitted to the reflector, and then reflects the light and crosses the test channel again. The reduction of light dispersion caused by smoke is proportional to the smoke concentration. The light spot transmitted to the reflector is larger than the reflective part, which makes it easy to debug and avoids test errors caused by thermal changes on the surface of the probe and reflector.
