mine explosion-proof dust sampler CCZ20 : 10～25L/min (adjustable)
- Product overview:
+ Dust sampler is a detector for measuring the concentration of floating dust in the ambient air.
+ According to GB-20964-2007 General Technical Requirements for Dust Samplers, JJG520-2002 Dust Sampler Appraisal Regulations, Q/320581FYK001-2008 Dust Sampler Enterprise Standards
+ The ExibI level in the GB3836.4-2010 standard (essential Safety type) explosion-proof design, suitable for underground coal mines and other workplaces containing explosive gas.
+ The sampler is equipped with two types of dust pre-traps,
+ Total dust pre-trap to determine the total dust concentration;
+ Respirable dust pre-trap to determine the concentration;
+ This pre-trap can be The respirable dust and non-respirable dust that are harmful to the human body are separated.
+ Can collect both respirable and non-respirable dust samples at one time.
+ Separation efficiency reaches the "BMRC" curve standard.
+ More reliable dust separation device.
+ The instrument is also equipped with a high-performance suction pump with no pulsation air flow, large load and negative pressure capacity, automatic timing sampling, stable flow, simple operation, easy to carry and so on.
