Item # Model 415N4, Model 415N4 Trace Oxygen Analyzer, Wall Mounted NEMA4 (IP65) Enclosure Rating

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.

Standard Cabinet: NEMA 4 Weather-proof steel cabinet with window.
Optional: 19" rack mount cabinet also available in some applications.

Applications
Light-duty analyzers for applications or environments that are less intensive. For continuous analysis of PPM levels of oxygen (O2) in clean / dry gas streams. Applications include blanketing mixtures, glove boxes, electronics, research, hydrogen/nitrogen mixtures, and many others.


Features
  • Touch-screen display for gas readings
  • Ranges available from 0 to 100 PPM to 0 to 9,999 PPM O2
  • Electrochemical O2 sensor is unaffected by hydrocarbons in the sample
  • Solenoid valves trap PPM O2 sample to avoid sensor depletion when analyzer is powered off
  • Easy-to-maintain, modular layout
  • Non-isolated 4-20mA recorder output


Options
  • Hi/Low gas and low flow alarms available
  • Serial output & data-logger package available
  • Light-duty pre-filter & condensate removal
  • Up to 6 other gases measured (depending on application)
  • Cabinet cooling available


Calibration
  • Nitrogen for zero
  • Air or analyzed calibration gas for span


Unique Applications
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.
