Mine Explosion-proof Dust Meter

1.Mine Explosion-proof Dust Meter Product Overview

Mine Explosion-proof Dust Meter is suitable for accurate on-site determination of dust concentrations in underground working environments in coal mines and displays readings directly.The Mine Explosion-proof Dust Meter (hereinafter referred to as the meter) is an instrument used to measure the concentration of floating dust in the ambient air based on the principle of infrared light absorption.The instrument is explosion-proof according to the MT163-1997 "General Technical Conditions for Direct-reading Dust Concentration Measuring Instruments" and Q/320582YLA013-2016 "CCZ1000 Direct-reading Dust Concentration Measuring Instrument" and the ExibI level (intrinsically safe) explosion-proof standard in GB3836-2010 Design a dust concentration measuring instrument that The separation efficiency of the respiratory separation device of the machine fully complies with the internationally recognized "BMRC" curve requirements, and 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, which provides a basis for accurate evaluation of workplaces.Provides reliable data on hygienic conditions, and the instrument is suitable for use in coal mines and other workplaces containing explosive and dangerous gases.

The instrument has compact structure, simple operation, large load and negative pressure capabilities, automatic timing sampling, stable flow, full Chinese LCD display, and easy portability.
