Product Overview
The deep-hole fixed-point rapid sampling device meets the requirement for achieving fixed-point rapid sampling during coal seam drilling and sampling processes. This instrument utilizes jet technology and multi-stage induction technology, enabling sampling without withdrawing the drill rod. It can achieve rapid fixed-point sampling at any point within 100m or a larger range in the coal seam within 5 minutes, complying with the GB/T23250 "Direct Determination Method of Coal Seam Gas Content Underground" requirement that "sampling time is less than 5 minutes and fixed-point sampling is achieved."
