The Nova FLEXI-NOVA Series Platform has been designed for continuous gas measurements 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, PPM-level O2 gas. This electrochemical type sensor is unaffected by most other gases in the sample including most hydrocarbons and acidic gases such as carbon dioxide (CO2), hydrogen sulfide (H2S), and sulfur dioxide (SO2). Typical O2 sensor life is 1-2 years or longer depending on measurement concentrations and sample gas exposure. The sensor may be easily replaced by the customer.

All sensors / detectors are temperature-controlled or temperature-compensated for maximum analytical stability. Easy calibration using touch-screen controls. Serial Output Package allows connection & data-logging to personal computers via a choice of USB / RS-232 / RS-485.

Unique Applications

N/A The O2 sensor in the Model 415 is not normally affected by gas stream composition. However, continuous or frequent exposure to high levels of acid gases such as carbon dioxide (CO2) and sulfur dioxide (SO2) can cause decreased cell life. All Nova analyzers are built using proven technologies and techniques. If this product does not suit your application, please contact Nova at 1-800-295-3771. In many cases, we are able to build an analyzer specific to your needs.
