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.
