ERKA Precise Dual-Head Stethoscope

The ERKA Precise is a high end stethoscope featuring a dual-head brass chestpiece that can be used for auscultation of higher and lower frequencies in all medical fields. The bell features a non-chill rim and is used for auscultation of lower frequencies, while the special patented design of the dual-frequency diaphragm allows for auscultation of higher and lower frequencies. The separately-integrated spring and the parallel-running channels in the tubing transmit sound without loss and without adding extra grinding sounds from the chestpiece to the user's ear.

The ERKA Dual-Frequency Diaphragm

The floating membrane prevents sounds from being transmitted if it is deformed. The membrane is designed so as to withstand day to day use in the practice or clinic, and nevertheless ensures outstanding sound transmission. On the outside–the side that touches the skin–the stethoscope features a strong plastic diaphragm that protects the internal, highly sensitive and extra thin copper-beryllium diaphragm. The space between the two membranes provides extra resonance space and acts as a pre-amplifier. The ERKA dual-frequency diaphragm guarantees perfect auscultation results and a confident diagnosis.
