Erka Precise Stethoscope has open bell side, which allows the physician to determine the lower frequencies. The membrane side is equipped with the ERKA. Dual membrane which, thanks to its unique, patented construction, allows the most sensitive auscultation of both low and high frequencies. The ERKA dual-channel tubes have two internal channels to reach each ear separately. This maximizes the quality of sound transmission and minimizes external noise. 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.
