MDF 797 CLASSIC CARDIOLOGY Cardiology stethoscope, black

Excellent listening properties.
Stethoscope head - the classic double-sided head is made by hand from polished stainless steel, which provides excellent listening properties. The membrane made of the most sensitive material perfectly improves the sound quality. The perfect tightness of the membrane is ensured thanks to the support ring, which enables optimal amplification and high frequency of heart and lung transmission at frequencies of 100 to 1000 Hz. On the other hand, a very large and deep funnel allows you to listen to tones with a frequency of 20 - 100 Hz.
Convex membrane.
The membrane is convex with a durable support ring made of non-cooling PVC material for greater patient comfort. Classic Cardiology provides excellent improvement in heart, lung and blood pressure.
Acoustic hose.
The ergonomic shape of the components guarantees advanced comfort. The combined double acoustic hose increases the internal quality of the acoustics. An individually guided channel reaches each ear. Enclosing both channels in a single Y-shaped conductor maintains high quality while eliminating internal damping and external interference. The acoustic hose is made of non-crumbling and non-sticky quality PVC without latex.
Olives ComfortSealTM.
The headphones are equipped with a double spring and the soft MDF ComfortSealTM earcups are ergonomic and designed for long-term comfortable use. The earpiece is also made of stainless steel and is also equipped with a double spring.
