CLASSICAL REINVENTION
ProCardial® ERA®
The MDF® ProCardial® ERA® is the very first stethoscope of its kind. We promise, you’ve never seen a stethoscope like this and you won’t believe how light it is. In addition to the redesigned lightweight headset and patented sound-sealing A2X tubing, it features a convertible chestpiece with 3 real bells and 3 separate diaphragms in adult, pediatric, and infant modes.


CONVERTIBLE CHESTPIECES
Sound Check 1-2-3
The aluminum chestpiece comes fitted with bells and diaphragms in adult, pediatric and infant sizes allowing for quick conversions to nine different configurations. Each diaphragm features a non-chill retaining ring to provide a secure acoustic transmission for heart and lung sounds.

TRUE BELL & TRUE DIAPHRAGM
Sound Judgement
Take the guesswork out of auscultation with our True Bell & True Diaphragm dual-head chestpiece. The bell side focuses on low frequency sounds while the Ultra-sensitive Diaphragm handles high frequencies.

DENSER, LONGER TUBING
Sound Barrier
Constructed of latex-free PVC, the patented A2X is an A-Type redesigned with an X configuration and dual input. It maintains two sound transmission channels to preserve acoustic integrity while sealing out extraneous sounds, even in high-noise conditions. The thicker, denser PVC construction prevents cracking and wearing.

ERGONOMAX™ HEADSET
Sound Fit
Our patented ErgonoMax™ headset is pre-angled and tension adjustable, allowing for a tailored fit. The dual-leaf spring adds a second layer of durability, ensuring the structural integrity of the headset and prevents breaking when tension is increased.

ATTACHMENT CLIP
Sound Arrangement
Using the included attachment clip, the adult and pediatric diaphragm assemblies can be easily carried and replaced with adult, pediatric, and infant bells.
SAFETYLOCK™
Safe & Sound
Our patented SafetyLock™ prevents accidental puncturing of the eardrum from loose eartips coming off during your practice.
Pat No. ZL 201020279423.9
CLEAR SILICONE EARTIPS
Sounds Comfy
