Tachometer

• Model NO.: DT-2859

Product Description

Photo/Contact Tachometer
Model: DT-2859
 

Applications
The Tachometer is used to measure rotative velocity, surface speed, frequency of motor. Applicable to the product departments of motor, fan, paper-product, chemical fiber, washing-machine, automobile, airplane, steamer etc. Multifunctional, one instrument combines PHOTO TACH.(RPM) & CONTACT TACH. (RPM , m/min, ft/min ). It can also be applied to the measurement of Frequency, Cycle, Pulse Times, Pulse Distance, Userdefined Pulse Distance, etc.

Features

* Multifunctional, one instrument combines PHOTO TACH.(RPM) & CONTACT TACH. (RPM , m / min, ft / min ). It can also be applied to the measurement of Frequency, Cycle, Pulse Times, Pulse Distance, User-defined Pulse Distance, etc.
* Digital display with no guessing errors.
