Handcrafted Since 1971 | Lifetime Warranty
MDF® ProCardial ERA Lightweight Cardiology
The patented handcrafted lightweight aluminum dual-head chestpiece is precisely machined and hand polished for the highest performance and durability. The patented dual-output, full-rotation acoustic valve stem features SoundTight™ GLS technology to seal in sound, and the green indicator dot allows the user to easily identify the active sound channel. The chestpiece comes fitted with real 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 of 100Hz to 1000Hz, and the cardiology bells are crowned with non-chill bell rings to provide greater sound amplification and isolation of low frequencies (20Hz to100 Hz).
A2X >Constructed of latex-free and phthalate-free PVC, the patented A2X is an A-Type redesigned with an X configuration and dual input. It maintains two uninterrupted 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.
