The JH-GF1000 dust concentration detector adopts the principle of light scattering and is equipped with an imported high-precision processing core. It is mainly used to detect the concentration of dust in the workplace and is suitable for detecting coal dust and other dust in industrial and mining enterprises. It can detect and warn of exceeding the standard 24 hours a day. Prevent harmful effects on the health of workers due to high dust concentration or explosion accidents caused by high concentration, which may endanger life safety.
