Enhanced by an interchangeable bell and diaphragm assembly, the Prestige medical clinical cardiology stethoscope allows for a wider variety of diagnostic applications. The cone shaped bell side of the chest piece is deeper and perfectly suited to detect the lower frequency hart sounds between 20Hz and 660Hz while the snap on fiberglass diaphragm is uniquely ideal for detecting the higher frequency heart and respiratory sounds between 150Hz and 1000Hz. The latex free two tubes into one design ensure the clearest sound transmission as well as no worries about allergic reactions. The stainless steel construction ensures durability in both the yoke and binaural as well as the chest piece. Known throughout the industry for their superior acoustics, the Prestige cardiology is arguably the finest at providing auditory diagnostics. Prestige offers two sizes of ear tips to make sure their users are able to achieve a good acoustic seal, providing top of the line acoustics and amazing comfort. The lifetime warranty that includes free lifetime replacement parts lets you know that Prestige stands behind their equipment. A favorite of medical professionals everywhere, this model is perfect for doctors, nurses, vets, medical students, home health care workers, or any other medical professional that uses a stethoscope. With four color options to choose from, you can personalize this scope and match the color to your personality or typical outfit colors. If you’re outfitting a medical office, you may want to have one color for doctors, one for nurses and one for lab technicians making it easy for patients to keep track of who they are dealing with.
