Item # Model 460N4, Model 460N4 Sulfur Dioxide 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, percent and ppm-level SO2 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 Weather-proof steel cabinet with window

Unique Applications
Nova 460 / 461 analyzers are suitable for clean dry process gases only. Some gases may interfere with SO2 measurement; complete information on sample gas composition is required. 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.
