Even a single patient diagnostic tool can meet the highest of standards. MDF has attained those standards with the affordable, high-performance MDF® Singularis™ DUET™ Stethoscope. The 747 has a lightweight aluminum dual-head chestpiece that is precisely machined and hand polished. It's fitted with an ultra-thin fiber diaphragm. The bell has a non-chill bell ring for patient comfort. The full-rotation acoustic valve stem has a green indicator dot that allows the user to easily identify the active sound channel. The eartips are soft and provide a comfortable seal that keeps out extraneous noise.
