LB-CCHG1000 direct reading explosion-proof dust concentration detector

1. Overview
The LB-CCHG1000 direct reading explosion-proof dust concentration detector is an instrument used to determine the concentration of airborne dust in the ambient air based on the principle of infrared light absorption. This instrument is designed according to the enterprise standards of MT163-1997 (General Technical Conditions for Direct Reading Dust Concentration Measuring Instruments) and Q/320581FUK007 (LB-CCHG1000 Direct Reading Dust Concentration Measuring Instrument), as well as the Exibl level (Intrinsic Safety Type) explosion-proof design dust concentration measuring instrument in GB3836.4-2000 standard. The respiratory separation efficiency of this instrument * meets the "BMRC" curve requirements of *, and can accurately and timely reflect the control of respiratory dust inhaled by dust collectors and the pollution situation of dust in different dust workplaces, providing reliable data for accurately evaluating the hygiene conditions of workplaces. This instrument is suitable for underground coal mines and other workplaces containing explosive gases.

Application scenarios:
Suitable for dust monitoring in labor departments of industrial and mining enterprises
Health quarantine testing
Environmental protection testing, pollution source investigation
Municipal tobacco monitoring
