JH-GF1000 Dust Concentration Detector
The JH-GF1000 dust concentration detector uses a light-scattering principle and an imported high-precision processing core. It is designed to monitor dust concentration in workplaces and to detect coal dust and other dust in industrial and mining enterprises. It continuously detects and warns of exceeding the standard 24 hours a day to help prevent health risks for workers and reduce danger to life safety from explosion accidents caused by high dust concentrations.
