Salient Features :
- Stepless, smooth speed adjustment from 3,000-35,000
rpm.
- Precision machining achieved bur eccentricity within
0.02mm.
- DC coreless micromotor used for quick motor response
and smoother rotation over full speed range.
- The handpiece is compact, lightweight, and well fits
to user's hand. User can use it for a long period of
time without fatigue.
- The handpiece is provided with the special dust proof
mechanism which prevents entry of cuttings and other
foreign substances into the ball bearnings, thereby
ensuring high durability.
- Functions and performance desired for
laboratorymotors are highly emphasized in conception and
packaged in a cutely designed control unit.
- Over-current protector functions immediately and
stops the micromotor for safety.
- Electronically achieved to minimize impact at start
to the operator's hand, and this also extends device
longevity

Details :
The audiometer has been designed to offer the basic needs, such
as pure-tone, speech, noise-narrow band & wide band +10 &
+20 dB facility with 5 dB steps. Besides this it have been
provided with additional tests such as Auto, Stenger, ABLB for
much more analytical approach to audiological measurements.
Provisions of toggle L.R. provides facility for switching
between left & right for quick measurement confirmations.

Details :
Children who are hard of hearing from infancy or have gained
hearing at a developed age, need to help to learn to speak. They
need to know words, their pronunciation, meaning and usage. With
patience and understanding, parents and teachers can achieve
heart-warming results.
