ABS-Plastic Housing Digital Laser Tachometer for Chemical Fiber , Washing-machine
Summary:
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.
Used to measure rotative velocity, frequency of motor. Applicable to the product departments of motor, fan, chemical fiber, washing-machine, automobile, airplane, steamer etc.
Features
* Measuring RPM is safe & accurate without attachment to object.
* 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.
