Brief introduction: Dynamic gas calibration device by multiple mass flow controller to output different proportions of flow, implement configuration mixing the gas concentration of gases. Can be widely used in gas flow measurement with the preparation of standard gas sample verification and testing, calibration gas analysis, etc. Features: 1. The gas composition and flow rate, the dilution ratio, optional; 2. With automatic distribution and manual with qigong can, from manual calculation of dilution ratio; 3. A single gas can be produced, also can make a variety of gases at the same time; 4. The mass flow controller USES the closed-loop fuzzy control technology, fast response speed, flow control accuracy; 5. Dilution gas pressure and the gas pressure real-time monitoring, ensure that meet the requirements of the instrument air supply pressure; 6. A large screen LCD, menu structure, operation simple and convenient; 7. Many signposts gas input interface, from change of multiple cylinders; Technical indicators: F.S flow linearity: + / - 0.5%; Dilute gas flow range: 0 ~ 5 SLM (0 ~ 10 SLM, 0 ~ 20 SLM optional); The cylinder gas flow range: 0 ~ 50 SCCM (0 ~ 10 SCCM, 0 ~ 100 SCCM optional); Dilution ratio: 200:1 ~ 2000:1 (4 road mass flow controller); Response time: 20 s; Input pressure: 150 kpa to 250 kpa. Shape size (W * H * L) : 482 mm * 178 mm * 450 mm Weight: 14 kg
