Contact Tachometer Tachometer Speedometer – WL-147 WELLHISE HT522

WL-147 WELLHISE HT522 CONTACT and non-contact tachometer is a device used to measure the revolution of a rotating object. It can be used as non-contact or contact, meaning that the device does not need to touch an object to take a measurement.

The HT522 model is commonly used to measure the rotational speed of industrial machines, determine motor speed, control propeller speed and similar applications. The device is particularly important for monitoring the speed of rotating parts and evaluating their performance.
