The Nova FLEXI-NOVA Series Platform has been designed for continous gas measurments in applications and environments that are less intensive. Lab work, research, clean processes, pre-treated / pre-cleaned produced gases, and others, may benefit from the FLEXI-NOVA series. Depending on application, some light-duty sample conditioning features may be available. For clean process measurements, of certain binary gas mixtures such as H2 or He in Air. This analyzer utilizes a temperature-controlled, thermalconductivity (TC) cell for the required measurement. The cell produces a small millivoltage output which is directly proportional to the gas detected. The analyzer can be supplied with a pump or pressure regulator depending on customer requirement. All sensors / detectors are temperature-controlled or temperature-compensated for maximum analytical stability. Easy calibration using touch-screen controls. Serial Output Package allows USB connection & data-logging to personal computers.Standard Cabinet: NEMA 4 Weather-proof steel cabinet with window.Optional: 19" rack mount cabinet also available in some applications.
Product Specifications
Applications 0
Light-duty analyzers for applications or environments that are less intensive. For continuous analysis of a choice of many binary gas mixtures comprised of H2, CO2, O2, CH4, SO2, Ar, He, NH3, SF6, Air, and others. Applications include heat treating atmospheres, welding gas mixtures, blanketing gas mixtures, ammonia synthesis, gas purge monitoring, magnesium blanketing by SF6, and others.
