Additional details
The handcrafted stainless steel dual-head chestpiece is precisely machined and hand-polished for the highest performance and durability. The patented full-rotation acoustic valve stem features SoundTight™ GLS technology to seal in sound, and the green indicator dot allows the user to identify the active sound channel easily. The chest piece is fitted with an adult and pediatric ultrasensitive diaphragm, each sealed with a non-chill retaining ring to provide secure acoustic transmission for heart and lung sounds of 100Hz to 1000Hz. Using the included screw-on attachment, the pediatric side can be easily converted to an extra-large cone-shaped bell crowned with a non-chill bell ring to provide greater sound amplification and isolation of low frequencies (20 Hz to 100 Hz).
Constructed of thicker, denser, latex-free PVC, the dual-lumen non-stick acoustic tubing ensures sound efficiency, provides insulation for superior sound transmission, and seals out ambient noise while preventing the cracking and wearing that can occur from repeated use. The longer-than-average length allows a comfortable space between health professionals and patients. ErgonoMax™
The hand-polished, pre-angled stainless steel headset features a patented internal dual-leaf spring construction for durability and a custom fit. Soft silicone ComfortSeal™ ear tips (available in standard and small sizes) are clear for hygienic purposes and conform to the ear to seal out extraneous noise while ensuring extended use. Patented SafetyLock™ eartip adaptors lead the industry in user safety.
Included Accessories: 2 extra sets of ComfortSeal™ ear tips, cardiology bell conversion, spare ultrasensitive diaphragm, and ID tag.
