Mining direct reading dust concentration measuring instrument

Mining direct reading dust concentration measuring instrument

Product Description:

The CCHG1000 direct reading dust concentration measuring instrument 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 based on MT163-1997<General Technical Conditions for Direct Reading Dust Concentration Measurement Instruments>and Q/320581FYK007Direct reading dust concentration measuring instrument>ExibI level (intrinsic safety type) explosion-proof design dust concentration measuring instrument in enterprise standards and GB3836.4-2000 standards. The separation efficiency of the respiratory separation device of this instrument meets the "BMRC" curve requirements of *, and can accurately and timely reflect the quality of respiratory dust inhaled by dust collectors and the pollution status of dust in different dust workplaces. It provides data for accurately evaluating the hygiene status of workplaces. This instrument is suitable for underground coal mines and other workplaces with explosive gases.

The instrument has a compact structure, simple operation, high load and negative pressure capacity, automatic timed sampling, stable flow rate, fully Chinese LCD display, and is easy to carry.
