DT2234B type tachometer

First, the characteristics u measure RPM is safe and correct, do not close to the object. u very wide measuring range and high resolution u Finally, maximum, minimum, automatic storage, with "MEMORY" button to bring up one by one reading. u digital display to the positive RPM, do not have to guess or error. u tachometer use this expensive microprocessor, LSI integrated circuits, quartz time base to make correct measurements provide highly accurate and fast measurement time. u use of strong, durable parts, including a strong, lightweight ABS plastic outer absurd enough to ensure the maintenance and other use for many years, in order to comfort each hands, the outer structure has been noted sharpness.
