|Dual-membrane and optimal sound chamber geometry |For the examination of heart, lung and bowel sounds |Excellent sound precision

Erka Sensitive Stethoscope has two internal channels to reach each ear separately. This maximizes the quality of sound transmission and minimizes external noise. The reversible double chest-piece has an open bell side for the low frequencies and a membrane side for the entire frequency spectrum. The ergonomically shaped soft ear tips will fit your ear canals perfectly and block out external noise. All components used in an ERKA stethoscope can be cleaned and disinfected easily and thoroughly. The chest-piece of an ERKA stethoscope is made from hand polished and pore free chromed brass. Compared to aluminum or stainless steel, this surface is more resistant to germs and bacteria.
