Stereophonette

【Technical Data】
・Chestpiece
The monolithic Constrauction of the bell, coupled with diaphragm micro-phones of stainless steel, creates a quality stereophonic effect. Selective use of the bell and the diaphragm microphones is achieved by turning the microphones around the central shaft, as is done with conventional stetho-scopes.(Except Model No.333)
・Tube
The two-in-one construction of the sound tube makes the stethoscope free from friction noise.

【Reasons for“causing no pain to the ears”】
・Reason 1
　The spring applies soft pressure to te ears.
・Reason 2
　The angle of each auditory pipe can be adjust so that it perfectly fits the ear.
・Reason 3
　A seivel fitting allows the auditory pipe to move freely with the earpiece fixed into the ear, eliminating the frictional resistance between the earpiece and ear.
