The tachometer, sometimes referred to as an RPM meter, is a gauge that measures the revolutions per minute (RPM) of an engine. A tachometer is typically found in vehicles with an internal combustion engine and is used to determine whether the engine is idling, accelerating, or in top gear. Vehicles with manual transmissions are often equipped with a tachometer, but many modern cars and trucks with automatic transmissions have one as well. The tachometer is used by the driver to determine whether the engine is in a high-revving, high-RPM gear or a lower gear, which is better for highway driving or city driving.
In this guide, we’ll discuss the different types of tachometers that are available today and highlight some of the best tachometers available to purchase. We’ll also give you a few pointers on how to install a tachometer in your vehicle.

Things To Consider Before Buying A eqqus tachometer
This section of the guide is meant to help you know what to look for when buying an auto tachometer. This will help you to make an informed decision when choosing a model that will suit your needs.
Readability
One of the most important features of an auto tachometer is that it should be easy to read. The numbers on the gauge should be large enough to be seen clearly from a distance. In addition to this, the colors used to display the numbers should also be distinct.
This feature is especially important if you drive a vehicle with tinted windows or at night. If the numbers are not readable enough, you may have to get out of the car to see what the RPM is. This could be dangerous if you are still driving.
Weight
The weight of the auto tachometer is another important feature to look at. This is especially true if you plan to mount the gauge on your dashboard or windshield. If the gauge is too heavy, it may cause damage to the glass or ruin the adhesive tape.
Based on our experience, we would recommend that you get a model that is not more than 5 ounces in weight. This will make it easier to mount the gauge on your dashboard without worrying about it falling or being knocked off.
Functionality
It is also important to check the functionality of the auto tachometer before buying it. This is especially true if you have a specific need or want a specific feature. For example, if you drive a diesel engine, you may need a model that can show the RPM of both the idle and maximum.
Some models may also show the temperature of the engine. If this is something you need, you should look at the maximum temperature that the gauge can display.
Compatibility
Last but not least, it is important to check the compatibility of the auto tachometer before buying it. This is especially true if you are planning to buy a universal model. Most universal auto tachometers will work with a wide range of vehicles. However, there are a few exceptions.
For example, some models may not be compatible with a Honda Civic. If you are not sure if the model you are planning to buy will work with your vehicle, you should check the manufacturer’s specifications before buying it.
If you are buying the model for professional purposes or to work on your vehicle, you should definitely buy a model that is made specifically for your make

If you have a tachometer that does not have a built in kill switch, you can easily wire it yourself using an in-line fuse. Simply connect the kill switch wire to the negative battery terminal and connect the other side of the kill switch wire to the middle terminal of the fuse. Connect the positive terminal wire of the tachometer to the positive battery terminal.
You can use a toggle or rocker style switch.

Conclusion
The tachometer is a simple device that measures speed. It is used in various industries to measure the speed of rotating objects. There are various types of tachometers available in the market. The analog tachometer is the simplest and most basic type of tachometer. The digital tachometer is more advanced and accurate than the analog tachometer.
The strobe tachometer is also known as the variable-frequency strobe tachometer. It is more accurate than the other two types. The eddy-current tachometer measures the speed of a rotating object by generating magnetic fields. The magnetic fields pass through the object, and their speed is calculated.
