Providing reliable measurement accuracy, minimal maintenance and greater ease of use, the Danalyzer 370XA is designed for continuous online analysis of natural gas for applications such as custody transfer, power generation, and burner fuel/air ratio control. The Danalyzer 370XA provides a C6+ analysis similar to legacy Danalyzer GCs in a much smaller and simpler form. New and experienced users alike will appreciate the latest advances in technology, improved diagnostics, and intuitive local operator interface (LOI), all of which come standard. An advantage of the Danalyzer 370XA is the Maintainable Module™, which incorporates the analytical components in an easily removable module. The Maintainable Module™ can be replaced in the field in approximately two hours (including warm-up and purge), and can be maintained at the component level for cost-effective repair. Easy to use software assistants on the full-color LCD local operator interface reduce the need for specialized training by providing a step-by-step walk through of common operational and maintenance functions such as changing calibration gas, auto-valve timing and module replacement. The Danalyzer 370XA can be pole-mounted, wall-mounted or floor-mounted. No shelter is required for most environments.
