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 to determine the adsorption constants (a, b values) of coal for gas during the measurement of coal mine gas content. Based on these values and the actual gas pressure measured underground, the gas content per ton of coal seam can be calculated.

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, and free from strong magnetic interference around the laboratory.

2. Performance Characteristics

The device is designed with an integrated concept, incorporating the main systems of vacuum degassing and high-pressure adsorption internally. This replaces 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 and printed.

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 to operate, automatically outputs data results, and automatically fits the adsorption isotherm curve.
