The 3M Littmann Cardiology IV 6183 Limited Edition stethoscope grey, is engineered for healthcare professionals who demand the highest acoustic performance, even in challenging environments such as the ICU, ED, Cardiac ICU, and operating rooms. Its stainless steel dual-sided chestpiece features tunable diaphragm technology, allowing you to hear low and high-frequency sounds without repositioning. With a 40% larger chestpiece and 60% deeper bell than the Classic III, it offers exceptional sound clarity. The dual lumen tubing eliminates the rubbing noise of traditional double tubes, while the soft-sealing ear tips ensure a perfect acoustic seal and all-day comfort. The non-chill rim provides additional patient comfort during examination.
