Individual Dust Sampler CCZG-2A : Respirable dust: 2L/min
- Overview
+ Individual dust sampler is an instrument for measuring the average concentration of air dust in a work shift.
+ Accordance with GB-20964-2007 General technical conditions for dust samplers, Q/320581FYK001-2008 Dust Sampler Enterprise Standard
+ ExibI level (intrinsically safe) explosion-proof design in the GB3836.4-2010 standard,
+ Small sampling air pulsation, large load capacity, stable flow, simple operation, safe and reliable,
+ Convenient Carrying and other characteristics,
+ The separation efficiency of respirable dust meets the requirements of the "BMRC" standard curve
+ Especially suitable for use in underground mines and other workplaces that contain explosive gases.
