LITTMANN Cardiology IV Diagnostic Stethoscope Black Edition

Outstanding acoustics with improved perception of high-frequency sounds (large side, increased pressure). 3M Dual Frequency diaphragm technology allows stethoscope users to control the diaphragm by varying the pressure applied to the chestpiece, enabling different frequency ranges to be heard. With light pressure, lower frequencies are emphasised; with slightly stronger pressure, higher frequencies. The paediatric side of the chestpiece can be converted into a traditional open bell by simply removing the Dual Frequency diaphragm and replacing it with the supplied non-chill rim. The integrated dual-lumen tubing combines two sound paths within one tube, eliminating the distracting rubbing noises of traditional dual tubes. Durable, dirt-repellent tubing material free from natural rubber latex and plasticisers. Optimal fit and wearing comfort thanks to individually adjustable ear tubes with soft eartips. Overall length: 69 cm, total weight: 177 g, chestpiece weight: 87 g, diaphragm: Ø 43 mm and 33 mm.
