Sthethoscope chest piece

1. The chest piece For Stethoscope is made of zinc alloy materials.
2. Sound pickup effect is good, equipped with a cold ring, suspension adjustable vibration film technology.
3. The smaller the diameter of the outer end, the more accurate the location of the sound, and easy to close contact with the chest wall, but because its collection surface is small, the sound is weak. The outer diameter of the stethoscope head is larger, so the weak sound is easier to detect.
