QANTA Stethoscopes are designed to help you listen to hard-to-hear sounds in the process of performing detailed auscultation and assessment on patients. QANTA Zen Cardio III SS stethoscope's double sided chest piece is made from best quality 303 grade stainless steel with both Adult and Paediatric Diaphragm. It is precisely machined for enhanced performance and durability. It features dual tunable diaphragms with brass chrome plated rings. The larger diaphragm is used for adult patients whereas the smaller diaphragm is used for pediatric patients. Comfortably Angled Chrome Plated Frame is made of 5.5mm seamless brass pipe. The frame is positioned at an anatomically correct angle, for a proper fit into your ear canals using the ultra soft ear buds. The frame tension is adjusted for individual fit and comfort. Two-way tubing is made from latex free PVC. The superior design of the tubing provides high quality sound transmission. Specially designed seamless PVC tubing retains its shape and flexibility even after folding tightly into a pocket and is less likely to pick up stains. Soft Sealing Ear Knobs are made of synthetic material, thus providing a cushioning comfort to the ears. Once, placed in the ear canal, they provide excellent acoustic seal, thus preventing any external noises. QANTA Zen Cardio III SS stethoscope has high acoustic sensitivity. When the head of the stethoscope is positioned on the patient, the vibrations of the human skin give rise to high acoustic pressure waves travelling up to the listener’s ears. It is an ideal stethoscope for doctors, medical professionals and medical students and specifically for cardiac and pulmonary examination for both adult and pediatric use.
