GDS-D2 two-component dynamic gas distribution system Introduction: This two-component dynamic gas distribution system is used to prepare multi-component standard gases that are gaseous at room temperature. It has a wide range of applications and can be used for research such as multi-point calibration of sensors. The gas distribution system adopts the principle of gas mass mixing method and utilizes internationally advanced measurement and control technology. The equipment is stable and reliable, and the preparation accuracy is high. It is very convenient to calibrate gas analyzers and gas sensors. characteristic: 1. Compliant with HJ38-2017, HJ604-2017, HJ57-2017 calibration regulations and standards 2. Adopting well-known domestic and foreign gas mass flow controllers with guaranteed quality 3. There are flow mode and concentration mode 4. High precision 5. Stable and good 6. Good repeatability 7. High degree of intelligence 8. 7-inch TFT LCD touch screen 9. Built in gas database with up to 57 types 10. The entire gas path is made of polytetrafluoroethylene or 316L stainless steel pipes, with anti-corrosion and anti adsorption treatment 11. The standard configuration is two channels, and the flow range and number of channels can be specially customized according to customer usage requirements 12. Provide the calibration certificate and technical parameters of the China Institute of Metrology Technical parameters: Gas type: Suitable for inert or corrosive gases Dilution gas: nitrogen or air Gas distribution principle: principle of mass mixing method Number of channels: 2 channels (expandable to 12 channels) Flow range: Dilution gas flow rate: 0-3000ml/min (customizable) Sample gas flow rate: 200-1000ml/min (customizable) Outlet flow rate: Needle valve can be adjusted Concentration range: ppb∽100% Flow accuracy: ± 1.0% F.S Dilution ratio: It is recommended to be within 200:1. The smaller the dilution ratio, the higher the valve accuracy Input pressure: 0.2∽0.5MPa Operating temperature: -10 ° C to 70 ° C Humidity range: ≤ 80% RH (non condensing) Working power supply: 220VAC, 50 ± 0.5Hz External dimensions: 430X380x178mm Weight: About 7kg
System composition:
This system mainly consists of the following parts:
Two component dynamic gas distribution system
Computer and operating software (LED touch screen can also be used, so there is no need to equip computer and software parts)
The components of the system are as follows:
Two component dynamic gas distribution system
This system utilizes current measurement and control technologies, with stable and reliable equipment and high configuration accuracy. Fully automated control, simple and reliable operation. The device is integrated into one chassis. The appearance is simple and beautiful. The main equipment includes: mass flow controller, one-way valve, shut-off valve, gas mixing pipeline, etc. Due to the presence of flammable and explosive hazardous media such as methane, ethane, ethylene, acetylene, etc. The gas path and circuit control part of the gas distribution system are designed to be installed separately. At the same time, fans are installed in areas where flammable gas leaks may occur to ensure air circulation and prevent the accumulation of combustible gases. Ensure the safety of the system and personnel.
The system is designed with two component gas distribution methods, one of which is dilution gas and the other is source gas, using standard bottle gas as the gas source.
The system is equipped with two American * mass flow controllers, which can achieve a mixture ratio of two component gases.
There are up to forty to fifty types of gases in the system database, which can be directly retrieved and selected through a computer when in use.
