Reversible double-sided chest piece: Membrane and bell side for the widest variety of demands
Membrane : The convex prestressed membrane enables excellent resonance transmission through optimal skin contact
Double-tube system: With separately integrated yoke spring for lossless sound transmission
The perfect all-round talent
The seca s 20 has versatile applications with its reversible double-sided chest piece and is thereby the ideal all-round talent for a reliable first analysis. Whether listening to the heart (membrane side) or lungs (bell side), simply reverse the chest piece to switch on the respective range and minimize background noise. The two separate inner channels in the tube also ensure lossless sound transmission. The convex prestressed membrane guarantees perfect skin contact for perfect resonance and sound transmission.
