3M Littmann Lightweight II S.E. Stetho, 2450, 28" Black Tube

The 3M™ Littmann® Lightweight II S.E. Stetho is an ideal entry level instrument, with a tunable diaphragm, dual sided chestpiece, and reliable acoustic performance. Its teardrop shape makes auscultation around blood pressure cuffs easier.

The 3M™ Littmann® Lightweight II S.E. Stetho provides reliable acoustic performance for taking blood pressure readings and making limited physical assessments of adult patients. Weighing just 118 grams, it’s the lightest of all Littmann adult stethos, making it more comfortable for caregivers who wear their stethos all day long.

The Lightweight II S.E. stetho is an entry-level instrument that offers a surprising number of beyond-the-basics features such as a tunable diaphragm, dual-sided chestpiece, and adjustable headset. It’s a good choice for medical professionals such as LPNs, licensed vocational nurses, certified nursing assistants, and nursing students.

Tunable diaphragm technology—a 3M invention—lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds. This time-saving feature allows the care provider to focus on the patient, while the non-chill diaphragm and rim provide patient comfort.

Resilient tubing retains its shape and flexibility even after folding tightly into a pocket. Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes. Snap-tight, soft-sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove.

Next-generation tubing is not made with natural rubber latex, a benefit to sensitive medical professionals and their patients. And, to play its part in the protection of human and the environment, the next-generation tubing does not contain phthalate plasticizers.

The Lightweight II S.E. stetho is made in the USA for consistent quality. It comes complete with large soft-sealing eartips and instructions.
