  • Page 5: Introductory Notes

    I. INTRODUCTORY NOTES A. PREFACE Thank you for selecting an ATLAS lab corrosion test cabinet. Our success is measured, first, by your selection of a cabinet that is manufactured to our Total Quality standards and, second, by your continued satisfaction. Our commitment to total quality extends beyond manufacturing, and continues well into your future.

  • Page 6: Bcx Series Overview

    ATLAS manufactures the BCX cabinet using advanced fiberglass, providing high corro- sion resistance. State of the art techniques ensure longevity and strength. This cabinet will not rust from corrosive solutions that are used in many testing processes. ATLAS’ all plastic design provides a “natural” insulation that helps make testing conditions consistent, repeatable, and controlled.
