The Schweitzer™ Classic is a single-tubed stethoscope. The solid yet light stainless steel chestpiece has a bell and a tunable diaphragm. The tunable diaphragm in the Schweitzer™ Classic ensures that low frequencies become audible by exerting slight pressure on the surface of the skin.
The Schweitzer™ Cardio III is a double-tubed stethoscope. This enables the Cardio III to produce excellent acoustical performances. The stethoscope is a 2-in-1 stethoscope with a double diaphragm, making the stethoscope a must for doctors who treat both adults and children.
