This universal stethoscope (Ri-Rap) can be used for a wide range of applications, thanks to its double chest-piece and tube system. It delivers impressive acoustics in all frequency ranges. It’s a nicely built device with its heavy chromium-plated double chest-piece and special membranes. There are two membrane sides that can be quickly and easily refitted with enclosed bells. The double tube feature has separate sound-conducting pathways for each ear. This guarantees quality audio-conductivity. Three replacement bells, each with a transparent membrane, and two extra pairs of replacement ear-tips are included.
