The gas inspector is an external instrument for checking the gas leakage concentration. It mainly refers to the handheld/fixed gas inspector. Gas sensors are primarily used to check for the presence of gases in the environment.

The gas analyzer analyzes the appearance of the process of measuring the gas composition. In many production processes, especially in the production process of chemical reactions, automatic control based on physical parameters such as temperature, pressure, flow rate is often not acceptable. Because of the wide variety of gas being analyzed and the variety of profiling principles, the variety of gas analyzers is complex. Commonly used are thermal conductivity gas analyzers, electrochemical gas analyzers and infrared absorption analyzers.


The flammable gas detector is a tool for external inspection of gas leakage concentration. It is a safety protection instrument.

The gas detector is a process for measuring the composition of a gas component and examining the composition of the gas.

In principle

In principle, the gas sensors are used to measure, which is basically the same.

scenes to be used

The four-in-one gas detector is widely used in on-site inspections in petrochemical, coal, metallurgy, chemical, municipal gas, environmental monitoring and other places. It can realize the measurement needs of special occasions; it can conduct gas concentration exploration or leakage exploration for tunnels, pipelines, tanks, confined spaces, etc.

Gas analyzers are required to supply pure nitrogen to clean the air chamber of the instrument and reduce noise to ensure maximum stability of the instrument.

The top air body analysis instrument is used for sealing the determination of oxygen, carbon dioxide gas content and mixing fraction in packaging bags, bottles, cans and the like; suitable for rapid and accurate in the packaging line in the production line, warehouse, laboratory and the like. The content and share of the gas components are evaluated to guide production and ensure that the shelf life of the goods is achieved.
