Proscope 640 Sprague Scope features an improved valve mechanism that virtually eliminates acoustic leakage and a chestpiece key to facilitate after market service.
The threaded chestpiece drum is made of chrome-plated zinc, which permits the use of five interchangeable chestpiece fittings. The five interchangeable fittings included are an adult and pediatric diaphragm, and three bells (1 1/4", 1", 3/4") allowing a complete diagnostic capability on most patients.
The diaphragm and bell are a traditional time proven design for detecting the broadest possible range of high and low frequency sounds. Ultra Adsoft Threaded eartips are included for the ultimate in acoustic performance and wearer comfort along with a chestpiece key for removal of worn or damaged diaphragms.
