Active Gas Pressure Rapid Tester Technical Manual
Product Overview
This device is developed based on the active pressure measurement and sealing method proposed by Academician Zhou Shining of the Chinese Academy of Sciences. It is a professional instrument specifically designed for measuring coal seam gas pressure. Featuring innovative sealing materials and a modular design, it is suitable for on-site detection needs in various coal seam bedding roadways.
Technical Features
1. Ease of Operation: Simplifies the sealing process for quick installation
2. Measurement Reliability: New composite materials ensure accurate pressure transmission
3. Economic Practicality: Main structure can be reused over 200 times
4. Environmental Adaptability: Ensures stable measurement under coal seam conditions with f≥0.5
