Hand Held Mechanical Tachometer

Hand-held mechanical tachometers are instruments used to measure the rotational speed or revolutions per minute (RPM) of a rotating object. They fall under the supply class of Liquid And Gas Flow, Liquid Level, And Mechanical Motion Measuring Instruments in the supply group of Instruments And Laboratory Equipment.

These tachometers are typically portable and designed to be held in the hand while taking measurements. They are commonly used in various industries such as automotive, manufacturing, and maintenance to monitor the speed of rotating machinery, engines, motors, and other mechanical systems.

Hand-held mechanical tachometers usually consist of a mechanical mechanism that converts the rotational motion of the object being measured into a visual display of RPM. They often feature a rotating shaft or wheel that comes into contact with the rotating object, causing the tachometer to register the speed.

Some hand-held mechanical tachometers may also include additional features such as a digital display, memory storage, and the ability to calculate and display other parameters like total revolutions or elapsed time.

Overall, hand-held mechanical tachometers are essential tools for accurately measuring and monitoring the speed of rotating objects in various industrial applications.
