The construction of the patented ERKA. dual-membrane allows for an additional resonance chamber which optimizes the sound.
Highly polished and chromium-plated for a non-porous surface, the brass chest-piece ensures perfect surface hygiene. The reversible double chest-piece has an open bell side for the low frequencies and a membrane side for the entire frequency spectrum.
Two internal channels run parallel in the stethoscope tubing. This prevents the friction noises caused by two separate tubes. Through the separately integrated spring in the tube, there is no acoustic loss from the chest-piece to the ear.
The standard 15° inclined binurals can be individually adapted to the ear canal characteristics of the user
The ergonomically designed, super soft ear tips create an excellent acoustic seal against external noise interference and maximize wearer comfort and fit.
