Fully Automatic Gas Adsorption Constant Measuring InstrumentWY-98A

Product Introduction

The Fully Automatic Gas Adsorption Constant Measuring Instrument (hereinafter referred to as the instrument) is primarily used in the process of determining coal mine gas content to measure the adsorption constants (a, b values) of coal for gas. Based on these values, the gas content per ton of coal seam can be calculated using the actual gas pressure measured underground.

Usage Environment and Performance Characteristics

1. Usage Environment

（1）Operating temperature: 0～40℃;

（2）Relative humidity: ≤95%;

（3）Atmospheric pressure: 80 KPa～106 KPa;

（4）Mechanical environment: Suitable for environments without significant vibration and impact; the laboratory should be free from strong magnetic field interference.

2. Performance Characteristics

The device is designed with an integrated concept, incorporating the main systems of vacuum degassing and high-pressure adsorption internally. This changes the traditional decentralized operation mode, improving testing efficiency and accuracy;

The device features a high degree of intelligent operation, with automated and intelligent experimental processes programmed into the system control software. It is easy to operate, provides scientifically accurate data, and reduces human error;

The entire measurement process is automatically controlled without the need for manual operation; the constant temperature water bath automatically drains water and includes a water level indication function;

Data charts are collected under computer control, and experimental reports and charts can be customized for printing;

The high-pressure adsorption process is controlled by solenoid valves, automatically adjusting different pressure points and capturing real-time data;

The data analysis software features a user-friendly interface, is simple and easy to operate, automatically outputs data results, and automatically fits the isothermal adsorption curve.
