《XY-HZ1000Portable direct reading dust analyzer》The enterprise standard, MT394 respiratory dust measuring instrument sampling efficiency determination method, dust sampler, and ExibI level (intrinsic safety type) explosion-proof design dust concentration measuring instrument in GB3836.4-2010 standard. The separation efficiency of the respiratory separation device of this instrument fully meets the internationally recognized "BMRC" curve requirements, 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, providing reliable data for accurately evaluating the hygiene status of workplaces. This instrument is suitable for underground coal mines and other workplaces containing 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.
