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.
Cabinet: NEMA 4 cabinet with Hazardous Area Purge System; available for Class 1 Div1 or Div2 hazardous areas

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.
