Mine Explosion-proof Dust Meter

1.Mine Explosion-proof Dust Meter Product Overview

Mine Explosion-proof Dust Meter is used to measure dust concentration in ambient air, and is suitable for detecting coal dust and other dust in industrial and mining enterprises.Mine Explosion-proof Dust Meter (hereinafter referred to as the measuring instrument) is an instrument used to measure the concentration of suspended dust in ambient air based on the principle of infrared light absorption.The instrument is designed according to the technical conditions of MT163-1997 "General Technical Conditions for Direct-Reading Dust Concentration Measuring Instruments" and Q/320582YLA013-2016 "CCZ1000 Direct-Reading Dust Concentration Measuring Instrument" and GB3836-2010 standard ExibI level (intrinsically safe) explosion-proof design dust concentration measuring instrument.The separation efficiency of the respiratory separation device of the instrument fully meets the requirements of the internationally recognized "BMRC" curve, and can accurately and timely reflect the quality of respirable dust inhaled by dust-exposed personnel and the pollution status of dust in different dusty workplaces, providing reliable data for accurately evaluating the sanitation status of the workplace.The instrument is suitable for underground coal mines and other workplaces containing explosive dangerous gases.

The instrument has the characteristics of compact structure, simple operation, large load and negative pressure capacity, automatic timed sampling, stable flow, full Chinese LCD display, and easy to carry.
