Descripción del producto

A patented tuneable diaphragm on one side, with the added benefit of a traditional bell on the other.
The tuneable diaphragm on the 3M Littmann Classic II SE allows you to listen to high and low frequency sounds by simply adjusting the pressure used during examination.
Firm pressure allows you to listen to high frequency sounds- ease off to light contact and the diaphragm instantly switches to let you hear low frequency sounds (previously heard using the traditional bell).
You no longer need to remove and replace the chestpiece during auscultation when using the tunable diaphragm on the Littmann Classic II SE.
