Proscope Stethoscopes & Diagnostic Instruments

Proscope, made by American Diagnostic Corporation (ADC), is the go-to line for clinicians who need dependable acoustics without the premium price tag. These are the workhorse instruments you'll find clipped to the pockets of nursing students, EMTs, home health aides, and busy clinic staff — lightweight, easy to clean, and built to survive daily rounds and the occasional drop.

The Proscope 660 Classic is the range's mainstay: a single-lumen tube, aluminum binaurals, and a molded chestpiece tuned for clear heart, lung, and blood pressure sounds. It comes in several colors (660M, 660N, 660W) so you can match a uniform or simply tell yours apart on a shared shift. Need a lower profile? The 664Y is a bell-free version with an ABS chestpiece and a 1-3/4 inch diaphragm — a solid pick for routine assessments and BP screening where you don't need a dedicated bell.

For pediatric and neonatal work, the Proscope 676 Infant uses a smaller diaphragm sized to a baby's chest, giving you accurate readings on little patients without spillover noise. The 662 Bowles offers a single-sided, non-chill design that's comfortable against the skin and fast to place — handy for quick vitals in triage or a crowded clinic.

Rounding out the diagnostic lineup is the ADC Diagnostix 5211 Otoscope, a standard-type, battery-operated ENT scope with a 2.5V lamp for ear canal and tympanic exams — a practical companion for any exam room or portable kit.

Not sure which chestpiece style suits your practice? Choose a dual-head or bell-equipped model if you assess both high- and low-frequency sounds; a single-diaphragm model like the 664Y works well for general screening.
