Burdick Quest Stress Test System

The Quest system is right for offices looking for value, simplicity, and increased patient throughput. The system is easy to use because it features a touch screen with convenient pull-down menus for intuitive workflow. Burdick's proprietary Logistep guide walks users through the test by highlighting the next step. We put everything you need on one screen, so there's no need for toggling among screens. And to save you time, we added an easy way to correct unintentional phase changes without having to start all over again.
