3M Littmann Cardiology IV Stethoscope – Dual-Sided Tunable Diaphragm for Adult & Pediatric Patients

Description

The 3M Littmann Cardiology IV Stethoscope Model 6240 is a high-performance diagnostic tool designed for healthcare professionals who demand precision, versatility, and comfort. Its dual-sided tunable diaphragm allows clinicians to hear both high- and low-frequency sounds from one side, reducing sound interference and improving accuracy.

Built for critical care, cardiology, and dynamic environments such as ICU, ED, and step-down units, the stethoscope features dual-lumen tubing for superior sound quality, soft-sealing eartips for comfort, and a non-chill bell sleeve for enhanced patient care. The adult diaphragm measures 1.7″ and the pediatric diaphragm 1.3″, easily interchangeable with the included bell sleeve.

Designed to detect subtle heart and lung sounds, including S3 and S4 gallops, aortic stenosis murmurs, and faint pulmonary anomalies, this stethoscope ensures reliable auscultation in demanding clinical situations. Made with latex-free tubing resistant to oils and alcohol cleaners, and weighing only 177g, it balances durability with ergonomic comfort.

Available in multiple chestpiece finishes (high-polish rainbow, black, silver, champagne) and tube colors (hunter green, navy blue, black, raspberry), the Littmann Cardiology IV also comes with a 7-year warranty. Trusted worldwide, it helps medical professionals diagnose and monitor patients with confidence.
