  • CHD-LH93 is an optical smoke detector, which works according to the principle of sensing smoke particles. With unique structural design and photoelectric signal processing technology, it has the functions of dust-proof, insect-proof and anti-external light interference. The machine combines microcomputer technology to analyze and process the data of induced smoke particle concentration, and can monitor the remote smoke concentration through computer software in real time. The product features beautiful appearance, easy installation and use, built-in air convection fan, remote monitoring of smoke concentration, local alarm output and so on.

    Function description: The machine has a good response to the visible smoke caused by slow smouldering or open combustion, and can accurately detect the smoke. When the smoke concentration exceeds the limit, the sensor generates an audible and visual alarm and outputs an alarm signal to the collector.

    Application: It is suitable for smoke monitoring in warehouses, computer rooms, hotels and other indoor environments.
