1_ The construction of the patented ERKA. dual-membrane allows for an
additional resonance chamber which optimizes the sound.
2_ The non-chill ring ensures patient comfort and protects the membrane.
3_ Highly polished and chromium-plated for a non-porous surface, the brass
chest-piece ensures perfect surface hygiene.
4_ Two internal channels run parallel in the stethoscope tubing. This prevents
the friction noises caused by two separate tubes.
5_ Through the separately integrated spring in the tube, there is no acoustic
loss from the chest-piece to the ear.
6_ The ergonomically designed, super soft ear tips create an excellent
acoustic seal against external noise interference and maximize wearer
comfort and fit.
7_ The standard 15° inclined binural can be individually adapted to the
ear canal characteristics of the user
