GDS-P2 Portable Dynamic Gas Distribution System Introduction: The portable dynamic 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 configuration accuracy is high. It is very convenient to calibrate gas analyzers and gas sensors. It is a product specially designed and customized for metrology and third-party testing institutions, convenient for calibration and testing of on-site gas equipment. characteristic: 1. Compliant with HJ38-2017 and HJ604-2017 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. Built in gas database with up to 57 types 9. Comes with a lithium-ion rechargeable battery that can work continuously for more than 10 hours on a single charge 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 of China Institute of Metrology Technical Parameter： Gas type: Suitable for inert gas or corrosive gas Dilution gas: nitrogen or air; When selecting air as the dilution gas, the equipment comes with an air washer and air compressor system, without the need for additional air cylinders. Gas distribution principle: principle of mass mixing method Number of channels: 2 channels Flow range: Dilution gas flow rate: 0-3000ml/min (customizable) Sample gas flow rate: 200-1000ml/min (customizable) 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: 260X230x290mm Weight: Approximately 8kg
System composition: Portable dynamic gas distribution system (standard with two components, expandable to three components) 7-inch LCD touch screen Standard gas output handle probe (extendable) and chassis strap Standard built-in air pump Built in DC rechargeable lithium battery (charging for 6 hours, can last for more than 12 hours continuously) Explosion proof types can be customized as needed for use in hazardous chemical environments. System Operation: 1) The gas distribution system is operated through a high-definition TFT touch screen, with sensitive response and simple operation. 2) Operation interface: There are two valve modes on the operation interface, one is flow valve mode and the other is concentration valve mode. We can freely choose the mode according to our own needs, and we can also pre-set the order of multiple gas concentration to achieve programmed automatic gas distribution. Standard configuration: GDS-P2 host, handle probe (extendable, about 3 meters) and chassis strap, PTFE tube, Chinese manual, certificate of conformity, warranty card, etc.
