1CCZG-2 Explosion proof Individual Dust SamplerOverview

CCZG—2Type individual dust sampler is an instrument used to measure the average concentration of dust in the air within a work shift. This instrument is based onMT162-95General Technical Conditions for Workplace Dust SamplersQ/FY-02-2005Enterprise Standards for Dust Samplers andGB3836.4-2000In the standardExibIThe explosion-proof design of the level (intrinsic safety type) has the characteristics of small sampling airflow pulsation, large load capacity, stable flow rate, simple operation, safety and reliability, and easy portability. The separation efficiency of respiratory dust meets the requirements“BMRC”The international standard curve requirements are particularly suitable for use in coal mines and other workplaces containing explosive gases.
