CCZ20Mineral dust sampler

The CCZ20 Dust Collector is an instrument used for measuring the concentration of suspended dust in ambient air. The instrument conforms to the GB/T 20964-2007 "General Technical Conditions for Dust Samplers" and the JJG520-2005 "Routine Inspection Procedures for Dust Samplers."Q/320582YLA00Model 1-2010Dust Sampler Enterprise StandardExibI explosion-proof design in accordance with GB3836.1-2000 and GB3836.4-2000 standards, suitable for coal mine underground and other workplaces with explosive gas hazards.

This sampler is equipped with two dust precollection filters: one for measuring the total dust concentration throughout the process, and the other for measuring the respirable dust concentration. This precollection filter can separate harmful respirable and non-respirable dust particles, allowing for the collection of both respirable and non-respirable dust samples in a single collection, with a separation efficiency that meets internationally recognized standards."BMRC" curve standard is a relatively reliable dust separation device. The instrument is equipped with a high-performance suction pump featuring pulseless airflow, with large load and vacuum capacity, automatic timing sampling, stable flow rate, easy operation, and portability.
