MDF® Classic Cardiology™ Dual Head Stethoscope

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 easily identify the active sound channel. The chestpiece is fitted with an ultrasensitive diaphragm sealed with a non-chill retaining ring to provide a secure acoustic transmission for heart and lung sounds of 100Hz to 1000Hz. The extra-large cone-shaped bell, crowned with a non-chill bell ring, provides greater sound amplification, isolation of low frequencies (20Hz to100 Hz), and patient comfort.

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 professional and patient.
