Electronic Micrometer (E.N-17) | | | 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

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.
