A tachometer is a commonly used instrument in the machinery industry, used to measure the rotational speed and linear velocity of motors. It can precisely measure the rotational speed of impellers, rollers, and shafts, and is widely used in industries such as motors, fans, washing machines, textiles, automobiles, airplanes, and ships. It adopts non-contact measurement, allowing measurement without contact with rotating parts. A high-definition large-screen backlight ensures accurate readings regardless of environmental changes, whether day or night
