The Adscope 608 Convertible Clinician Stethoscope combines Adjustable Frequency (AFD) Technology with a convertible design for maximum versatility. AFD technology allows the diaphragm to be tuned to enhance the high and low frequency responses in both adult and children diaphragms. The pediatric diaphragm can be converted to an extra deep bell for superior low-frequency response. Stainless steel construction and reinforced yoke molded flexible 22" PVC tubing ensure a lifetime of use. Adsoft Plus silicone eartips with snap-on connection provide superior wearing comfort and acoustic seal.
