GFC-5B type atmospheric samplerDetailed product description：

The GFC-5B explosion-proof individual dust sampler is specifically developed for the "GBZ/T 192 Workplace Air Dust Determination" standard. It is used for long-term or individual sampling and is used for sampling total dust, respiratory dust, and metal dust with a 1L-5L/min flow membrane sampling clip. Features: High performance air pump, strong load capacity, accurate high flow rate, ultra long working time, small size and light weight.
