The WTC Portable Gas Outburst Parameter Instrument is used to determine the prediction parameters for coal and gas outbursts, primarily measuring the drill cuttings gas desorption index K1 and the comprehensive index Kf (an index composed of the K1 indicator and the coal's firmness coefficient f value). When equipped with an optional portable accessory, it can measure the gas emission index V30 per ton of coal within 30 minutes after blasting at the working face, as well as the gas emission characteristic index Kc and other outburst prediction indicators, along with gas concentration within 8 hours. The WTC Portable Gas Outburst Parameter Instrument is an intrinsically safe intelligent measuring instrument for mining use, featuring a backlit LCD large screen display and Chinese menu-guided operation. It includes real-time clock, battery level display, and data preservation after power loss functions. The instrument boasts strong functionality, compact size, lightweight design, easy operation, and excellent moisture and dust resistance.
