FIELD: instrument engineering. ^ SUBSTANCE: invention concerns measurement equipment, particularly gas-analysis measurements, and can be used in all industries for calibration and verification of gas analysers. A gas analyser calibration and verification device accommodates temperature and pressure meters, output communication lines, a high pressure stabiliser, a passive liquid thermostat and aerator comprising a steel vessel designed for high gas pressure and filled by 30 - 60% with a liquid proportioned component through which a gas-carrier supplied through a bubbler flask is passed. The disclosed simple, relatively small generator of control gas mixture containing hexane, methanol, benzene and other components of high metrological (relative error 2-3%) and dynamic characteristics. ^ EFFECT: improvement of dynamic characteristics and design simplification of the device. ^ 1 dwg |
