Deep Hole Fixed-Point Rapid Sampling DeviceSDQ-73

Product Overview

The Deep Hole Fixed-Point Rapid Sampling Device meets the requirement for fixed-point rapid sampling during coal seam drilling and sampling processes. This instrument utilizes advanced aerospace jet technology and multi-stage ejection technology, enabling sampling without withdrawing the drill pipe. It can achieve rapid fixed-point sampling at any location within 100m or a larger range in coal seams within 5 minutes, complying with the GB/T23250 "Direct Determination Method of Coal Seam Gas Content Underground" requirement of "sampling time less than 5 minutes and fixed-point sampling".

Product Use

It enables rapid sampling and fixed-point sampling during coal seam drilling operations.
