The Graham Field 711-100 (Grafco/Labtron) is a specialized Bowles-type stethoscope designed for clinicians who prefer a single-head, high-sensitivity diaphragm for routine auscultation. It features a uniquely designed chrome-plated chestpiece with a raised stem, which is particularly effective for blood pressure measurement and general physical assessments. The flexible "Y" tubing and adjustable metal binaurals ensure high-fidelity sound transmission while maintaining a lightweight profile. This model is packaged in a bulk case of 100, making it a cost-effective solution for hospitals, training facilities, and emergency response kits.
