The Littmann Cardiology III Stethoscope is the stethoscope of choice among students and clinicians across all specialties. It combines outstanding acoustics and versatility and features a dual adult-sided and pediatric-sided chestpiece with 3M™’s patented tunable diaphragm that enables the user to utilize both sides of the stethoscope to monitor low-frequencies and high-frequencies. If you’re looking for versatility, look no further. The dual-sided chestpiece allows for examination of either children or adults in both low-frequency and high-frequency auscultation using 3M™’s “tunable technology”. Do you prefer a more traditional stethoscope? Convert the diaphragm from a closed-bell to a traditional open bell simply by removing the diaphragm on the pediatric side and installing the non-chill sleeve which is included with purchase. Hear fewer unwanted rubbing noises thanks to the special dual-lumen tubing design.
