Signature Series Electronic Stethoscope
The Signature Series Electronic Stethoscope captures sounds typically difficult to identify in standard stethoscopes. It is equipped with a built-in computer chip which eliminates aphonic and resonance effects for enhanced audibility, and audio frequency can be divided into 3 selective modes: Standard Bell, Diaphragm and Extended Diaphragm. The electronic amplifying system offers 8 different volume levels and the Signature Series Electronic Stethoscope automatically starts with the last used sound collection and volume mode. This is a great electronic stethoscope for the hearing impaired or for anyone who wants an amplified stethoscope that lets you hear loud and clear.
