Item # Model 470N4N7, Model 470N4N7, Methane Analyzer, ex-proof sensor housing with NEMA4 wall-mount control cabinet (two separate enclosures)


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, percent-level HC's as CH4 gas.

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.


Cabinets: Wall Mounted NEMA7 UL/CSA Explosion-proof sensor cabinet with NEMA4 wall-mount control cabinet (two separate cabinets)

Applications
Light-duty analyzers for applications or environments that are less intensive. For continuous analysis of Hydrocarbons (as CH4) in process gas streams using an infrared detector.


Features
  • Detector is temperature-controlled or compensated for improved analytical stability
  • High ranges available (up to 100.0%)
  • Low ranges available (to 1.00%)
  • Touch-screen display for gas readings
  • Built-in sample pump or pressure regulator
  • Non-isolated 4-20mA analog recorder output
  • Detector is reliable and non-depleting
  • Fast response (T90 - less than 15 seconds)


Options
  • Hi/Low gas and low flow alarms available
  • Serial output & data-logging available
  • Cabinet cooling available (on control cabinet only)


Calibration
  • On bottled CH4 gas for Span
  • On bottled N2 or Air for Zero


Unique Applications
The 470 Series analyzers are designed for detection of CH4 in non-corrosive gas streams. Also, the presence of higher order hydrocarbons will make the CH4 reading erroneously high. Detector response varies with each HC in the sample gas. Consult Nova for these applications. All Nova analyzers are built using proven technologies and techniques. If this product does not suit your application, please contact Nova. In many cases, we are able to build an analyzer specific to your needs.
