Automatic smoke and dust monitoring device
The smoke concentration monitor uses the principle of laser backscatter testing to measure the smoke concentration of the tested flue gas. The embedded high stability laser signal source of the smoke concentration monitor passes through the flue and irradiates smoke particles. The irradiated smoke particles will reflect the laser signal, and the reflected signal intensity will change proportionally to the smoke concentration. The smoke concentration monitor detects the weak laser signal reflected by smoke and can calculate the concentration of smoke and dust in the flue through specific algorithms.
