Brief introduction: MF - 4 b gas dilution device, is engaged in the study of more than 40 years of gas standard materials, gas measuring instruments national metrology technology, and revising laws and regulations, and has rich experience in the industry experts in design, material selection and parameters setting and quantitative; By engaged in instrumentation, computer software research and development experts in design and assembly. Developed the device stability, good repeatability and linear, preparation of standard gas accurate, reliable, easy to dissemination and traceability, quick operation, easy to use. On the front panel of the two rotor flowmeter has nothing to do with the distribution system, is used to control the inspection instrument or required flow analysis method. Panel is among 320 x240 color LCD display and touch screen, without any artificial calculation, just simple input by the touch screen and can complete distribution work. The operation is simple, convenient, fast, and a voice prompt. Technical indicators: Conventional diluted multiples of: 500:1, two way MFC flow control; Flow range, maximum dilution ratio according to user requirements to design and assembly: Flow repeatability: < 0.5% The uncertainty distribution: < 1% The preheating time: 30 min After the automatic zero: preheating automatic zero adjustment of MFC, or from the preheating repeat zero zero page Instrument power supply: 220 vac Using the environment: 5 ℃ ~ 45 ℃ Exterior size: 400 mm wide x 195 mm x 500 mm deep Instrument weight: about 8 kg
