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.
