(1) Measurement basis: JJG695-2003 “Verification Regulations for Hydrogen Sulfide Gas Detector”.   (2) Environmental conditions for hydrogen sulfide detector measurement: temperature (0-40) ℃; relative humidity not more than 85%; good ventilation, no interference with the measured component.   (3) Measurement standard: The extended uncertainty of the measured gas is ≤1.5% (k=2).   (4) The hydrogen […]

It is based on the principle that different gases have different thermal conductivity, and calculates the content of certain components by measuring the thermal conductivity of the mixed gas. This kind of analysis instrument is simple and reliable, and it is suitable for many kinds of gases, and it is a basic analysis instrument. However, […]

Infrared gas analyzer is a physical analysis instrument based on the principle of selective absorption of specific wavelength infrared light by different gas molecules. It is a typical optical, mechanical, and electrical integrated intelligent sensor system. Compared with other gas sensor systems, it has the characteristics of high sensitivity, fast response, various types of analysis […]

Can be adjusted automatically according to the surrounding air (depending on the measured component) High efficiency does not require calibration gas and accessories. Multi-layer detection ensures high accuracy and small lateral sensitivity. The sampling unit is easy to clean, reducing maintenance costs. User-friendly WINCE operating system, automatic data storage. Open interface structure (RS232, LAN, Internet). […]

Boot The following checks and operations should be carried out before starting to use the device: This instrument is an optical measuring instrument, which should strictly control the damage of the instrument by dust and moisture in the biogas; before measuring, the sampling head provided by the manufacturer should be connected to the sampling pipeline, […]

How to choose a junior high-efficiency air filter for an air handling unit? The fresh air unit mainly deals with the state points of the outdoor fresh air, while the air filter processing unit mainly deals with the state of the indoor circulating air. Compared with fan coil plus fresh air system and unitary air […]

Process analyzer for measuring gas composition. In many production processes, especially in the production process where there are chemical reactions, automatic control based on physical parameters such as temperature, pressure, and flow is often not enough. Due to the wide variety of analyzed gases and the variety of analysis principles, there are many types of […]

Common problems of rural biogas Build a new biogas digester, and the water level in the water pressure chamber of the biogas digester will drop after feeding. When the newly built biogas digester passes the water pressure test after adding the raw materials, the common problem is that the water column drops after the water […]

The thermal conductivity gas analyzer is based on an analysis principle called the name, and generally can analyze the concentration of hydrogen and argon. The instrument works based on the physical principles of different gas components with different thermal conductivity conditions. The platinum wire is used as the sensitive element to form an unbalanced bridge, […]

1 Infrared gas analyzer is to realize a series of chemical processes A gas analyzer or a gas analysis system is equivalent to a complete set of chemical process equipment. Therefore, the working process of the gas analysis instrument system is to realize a series of chemical processes. If you want to obtain correct data […]
