Gas Outburst Parameter Instrument 

1. Product Overview

The WTC3 Gas Outburst Parameter Instrument is a portable, intrinsically safe mining instrument. The parameter instrument allows manual input of sampling location, drill cuttings quality, drill hole depth, and exposure time parameters, and collects coal sample gas desorption pressure. It calculates the HK1 value based on the collected gas desorption pressure values. The instrument displays real-time sampling values, K1, and data curves, and allows users to query the pre-set parameters and calculation results for each record via an above-ground computer. The instrument has three analysis chambers that can simultaneously measure three sets of drill cuttings methane desorption indices K1. It features a compact design, lightweight construction, simple operation, reliable performance, and excellent moisture and dust resistance, making it an indispensable advanced piece of equipment for preventing methane disasters in coal mines.
