Brief introduction: The dilution apparatus for measuring, environmental protection, petroleum chemical industry, medicine, health, the centers for disease control and prevention, such as coal mine industry calibration gas analyzer, gas, toxic or harmful gases such as instrument to establish standards of measurement and provide standard device, to carry out verification, calibration and test standard gas that makes up the instrument; To investigate all kinds of gas meter, telemetry instrument and gas sensor standard gas that makes up a variety of performance; Ac/dc two power supply modes, small volume, indoor and outdoor can use. Used in the energy sector sulfur hexafluoride leak detector, purity of instrument verification and performance evaluation and preparation of standard gas; For coal mine methane tester, tester, such as carbon monoxide and oxygen verification and performance evaluation and preparation of standard gas, to calibration verification; Reference standard for gas analysis methods. Technical indicators: Conventional dilution ratio is: 200:1, two way MFC flow control (according to user requirements to design and assembly). Flow range, maximum dilution ratio according to user requirements to design and assembly: Flow repeatability: < 0.5% Traffic: linear error of plus or minus 0.3% or less 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 Power supply: 220 vac Using the environment: 5 ℃ ~ 45 ℃ Size: 380 mm x 195 mm x 250 mm wide Instrument weight: about 6 kg
