Atlas will introduce the Ci4000 Weather-Ometer®, which offers an enhanced digital control system that gives operators more flexibility and control of their accelerated weathering tests. The Ci4000 meets basic plastic testing standards such as ISO 4892-2, ASTM G151 and G155, as well as the SAE J1885 and J1960. One of the most notable changes is a modern colour TFT digital display with intuitive icons for easier interpretation of operating parameters and warnings.Memory capacity has been significantly increased, allowing for additional features and functions that were previously handled by external controllers. Today, with a single control system, operators can more efficiently analyze instrument performance, monitor test parameters, and perform calibration procedures.
