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. The seca s 22 is a stethoscope specially made for pediatricians. The child-friendly design on the membrane side of the double-sided chest piece makes it easier to make contact with smaller patients without causing fear and is suited for the auscultation of children to infants.
