Highly polished and chromium-plated for a non-porous surface, the brass chest-piece ensures perfect surface hygiene.
The best of the ERKA. tradition, reduced to the essentials. The geometry of the acoustic chamber - perfected over decades - in combination with the modern ERKA. dual membrane provides optimal auscultation over the entire frequency range. The auscultation is optimized by the high specific gravity of the brass body, as this reliably prevents noise interference.
The construction of the patented ERKA. dual-membrane allows for an additional resonance chamber which optimizes the sound.
