An hour meter functions to monitor the running time of your engine. In fact, in some cases, it is also equipped with the capability to trace the engine RPM (tachometer). Therefore, some say it a tach-hour meter. Because there are two functions in a single tool: tachometer and hour meter.
There are many benefits you can gain from monitoring your engine working hours. You can set your vehicles’ oil change interval, maintenance, service, etc. Some machines will work better with regular maintenance. Also, there is a typical machine that will last longer if threaded with regular service.
It is a very simple tool. You just need to stick it on near the engine. For a stronger grip, you could either tie or screw it. In the next step, you have to wrap around the hour meter’s wire to the spark plug. If the engine turns on, the hour meter will start off to counting. Vice versa, the engine stops, it stops counting. There is also an hour meter that works based on the vibration. The vibration models require no cable wrapping.
An hour meter is a nice investment. It can save your engine while it costs cheaply. If you are looking for the best hour meter, there are plenty of choices but you could start from our selection below.

How to Install Hour Meter on Dirt Bike
Maybe, most people use hour meter for their dirt bikes. Here is a simple video that we can recommend on how to install the hour meter on dirt bike.
How Does An Hour Meter Work?
As the name suggests, an hour meter counts the elapsed time of an engine has passed. Right the machine turns on, the hour meter starts off. Simply, you need to connect the wire to the spark plug by wrapping it around several times.
There is also a type of hour meter that works based on the vibration. This is the model you need to install onto your electronic devices (non-engine devices). As long as it emits vibration, the tool will work.
Some of the hour meters come with battery-powered. In this model, you can simply connect the wire to the spark plug and stick the hour meter at the place you are okay with as long as the wire is long enough to support. However, it’s recommended that you attach it not far from the engine.
On the other hand, several hour meters need external power to work off. It’s not a battery-powered model. You need DC or AC power in that case. Some of them work with limited AC/DC power range. It’s not weird if you find the one that works with both AC and DC power.
This AC powered model is suitable for the generator such as the Honda generator, compressors, electric motors, etc. While the DC-powered type is great to work for battery-operated things such as RTV, boat, lawn mover, lawn tracker, trucks, tractors, and even airplanes.
Aside from the power source, you need to know the look. Some models are digital, while the others are electromechanical. The electromechanical uses mechanical reading but still needs electric power. They may have different advantages. What we like from the electromechanical type is the reading will stay on there even though the power is off.
Before deciding to purchase an hour meter for your need, it’s necessary that you need to take time for some reading.
If you don’t have so much time to make some researches, then you are recommended to take the DiscoGoods above. It works for most purposes except for non-engine devices. You need that works based on vibration for that case.
If you have read further, you can select the ones that work best on DC or AC power. Finally, an hour meter is actually a nice tool to help you manage maintenance intervals so that you can save money from any damage to your valuable engines.
