GDS-EP2 Portable Explosion proof Dynamic Gas Distribution System Introduction: The portable explosion-proof 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, used for calibration and testing of gas equipment in hazardous areas that require explosion-proof requirements. 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 and good stability 5. Good repeatability 6. High degree of intelligence 7. Built in gas database with up to 57 types 8. Comes with a lithium-ion rechargeable battery that can work continuously for more than 10 hours on a single charge 9. The entire gas path is made of polytetrafluoroethylene or 316L stainless steel pipes, with anti-corrosion and anti adsorption treatment 10. Equipped with explosion-proof function (explosion-proof shell) 11. Provide the calibration certificate of China Institute of Metrology Technical parameters: 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 (expandable up to 3 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: 410X260x350mm Weight: Approximately 20kg
