Product Introduction
The Gas Emission Initial Velocity Tester (hereinafter referred to as the instrument) is a fully automated experimental device primarily used for measuring the key indicator in coal and gas outburst risk prediction—the initial gas emission velocity ΔP. It is designed to study the gas emission characteristics of coal and continuously measure the initial gas emission velocity within 0-60 seconds after adsorbing high-concentration gas under one atmospheric pressure.
The core component of the Gas Emission Initial Velocity Tester utilizes imported sensors, enabling computer detection and control. The entire testing process can be completed simply by pressing the corresponding keys as prompted by the computer interface, eliminating human-induced errors in experimental results. The test results are printed in the form of curve reports.

Fully Automatic Gas Emission Initial Velocity Tester Product Performance
1) This device is designed according to the AQ1080-2009 standard "Method for Determination of Initial Gas Emission Velocity (ΔP) of Coal." The experimental process is fully intelligent and automated, with smart calculation of data results, making operation simple and improving work efficiency.
2) The device's sensors and solenoid valves use imported components, ensuring excellent system airtightness and scientifically accurate test results.
3) The main unit design complies with safety ergonomic principles, featuring an integrated design that reduces manual operations and ensures a safe and highly reliable experimental process.
4) The main controller is designed using mainstream ARM technology.
5) High-precision ADC sampling, high integration, and dual isolation with surge absorption circuit design provide strong resistance to electromagnetic interference.
6) The system's fixed space calculation is calibrated using the gas displacement volume testing method, reducing manual calculation errors.
7) The device control software interface is compatible with XP, Win7, and Win10 systems, ensuring smooth operation and ease of use.
8) The sample chamber and connecting pipelines are made of alloy, addressing the drawbacks of traditional fragile glass and air leakage in gas path connections, thereby extending the device's service life.
9) The automatic rapid locking device for the test罐 ensures quick and automatic sealing, significantly reducing human-induced data deviations caused by manual locking, ensuring test data accuracy, and reducing the labor intensity of test personnel.
10) Automatic calibration upon startup, along with automatic calibration of the test space and fixed space, ensures more accurate test data.
