Omicron Compano is the first ever testing device for electrical testing – powered by a battery allowing to test for instance power plants like wind turbines without the need to use hundreds of meter of power cable. A unique versatile transporting system consisting of belts, backpacks and boxes that are joint flexibly by intelligent connectors allows unrivaled ergonomics and safety. As a rugged outdoor device the design conveys both uncompromising robustness and a strict link to the corporate design of OMICRON, dominated by sharp angles and precise edges. The jog-dial control enables fast access for various testing tasks.
