Multifunctional Portable Digital Tachometer with Wide Measuring Range And High Resolution
Brief Introduction:
Used to measure rotative velocity, surface speed, frequency of motor. Applicable to the product departments of motor, fan, chemical fiber, washing-machine, automobile, airplane, steamer etc.
A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common.
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.
* Wide measuring range and high resolution.
* The last value / max. value / min. value will be automatically stored in memory.
* The use of durable, long-lasting components, including a strong, light weight ABS-plastic housing assures elegant shape and ease of use.
* Use USB data output to connect with PC.
* Provide Bluetooth data output choice.
