CCHG1000 mine direct reading dust detector

Direct-reading dust meter for mining
Product Description
The direct-reading dust concentration meter is an instrument used to measure the concentration of floating dust in the ambient air based on the principle of infrared light absorption method. This instrument is based on the General Technical Conditions for Direct-Reading Dust Concentration Measuring Instruments and the Enterprise Standard for Direct-Reading Dust Concentration Measuring Instruments and the Standard Medium Level (Intrinsically Safe) Explosion-proof Design Dust Concentration Measuring Instrument. The breathing separation device of this instrument The performance fully complies with the internationally recognized r-curve requirements. It can accurately and timely reflect the quality of respiratory dust inhaled by dust-exposed personnel and the pollution status of dust in different dust workplaces. It provides reliable data for accurately evaluating the health status of workplaces. This instrument is suitable for use in coal mines. and other workplaces with explosive hazardous gases.
The instrument has the characteristics of compact structure, simple operation, large negative pressure capacity, stable automatic timing sampling flow rate, full Chinese LCD display, and easy portability.
