Digital smoke detector, line 500
Mod. 1043/501
SKU: 1043/501
Smoke detectors work on the principle of light scattering caused by smoke particles in the air.
The detector has the function of automatic gain control: a microcontroller calculates the reading compensation to maintain a constant sensitivity over time, correcting any increase in level caused by the deposition of dust inside the analysis cell.
Smoke detectors must be installed in places where there are no air currents that could divert the flow of particles produced by combustion and in places where normal activities carried out do not produce fires of gaseous materials.
