Tachometers

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.

Advantages of Tachometers

Tachometers give accurate and real-time RPM (revolutions per minute) data, allowing users to monitor the speed of an engine or motor. This information is critical for guaranteeing peak performance and avoiding damage.

Tachometers are useful diagnostic instruments for identifying engine problems. Mechanics can discover misfires, malfunctions, or abnormal wear and tear by observing unusual or fluctuating RPM data, resulting in faster and more successful troubleshooting.

Tachometers with warning systems can help keep engines from overrevving, which can cause serious damage. If the RPM exceeds a specified limit, the device can be designed to generate an alert or trigger an engine shut-off mechanism, therefore protecting the engine and its components.

The first mechanical tachometers were based on measuring the centrifugal force, similar to the operation of a centrifugal governor. Many companies from all over the world made different kinds of tachometers such as: mechanical tachometers, laser tachometers and the combinations of both. For instance we can mention some special brands like: testo, extech and etc.

One the most popular tachometers that MME Trading can supply is EXTECH RPM33. This instrument made by Extech Corporation is a combination of Contact and Laser Tachometer.
