The 32" stethoscope is more comfortable for some veterinarians, especially if they work with large animals. The chestpiece is ergonomically designed and has two sides: a bell and a diaphragm. The bell is used to listen to low-pitched sounds, such as heartbeats, while the diaphragm is used to listen to high-pitched sounds, such as lung sounds. • Specially designed • Durable • 32 inch
