Direct-reading explosion-proof dust tester CCHZ1000 is an instrument used to determine the concentration of floating dust in ambient air based on the principle of infrared light absorption.
The direct-reading explosion-proof dust tester is based on MT163-2019 "General Technical Conditions for Direct-reading Dust Concentration Measuring Instruments", Q 320581FYK010-2022 "CCHZ1000 Direct-reading Dust Tester" enterprise standard, MT394 respirable dust measuring instrument sampling efficiency measurement method, GB T20964 dust sampler and GB T3836The separation efficiency of the breathing separation device of the 4-2021 standard EXIBI level (intrinsically safe) explosion-proof design dust concentration measuring instrument and direct-reading explosion-proof dust tester CCHZ1000 fully conforms to the internationally recognized "BMRC" The curve requires that it can accurately and timely reflect the quality of respirable dust inhaled by dust collectors and the pollution status of dust in different dust workplaces, and provide reliable data for the accurate evaluation of the health status of the workplace.
Direct reading explosion-proof dust tester CCHZ1000 has compact structure, simple operation, large load and negative pressure capacity, automatic timing sampling, stable flow, full Chinese LCD display, easy to carry and other characteristics.
