A clamp meter is a tool that’s used by electricians and it combines a current sensor and a digital multimeter.
The clamp is used to measure current while the probes measure voltage. The hinged jaw of a clamped meter allows the user to clamp these jaws around a cable, wire or any other type of conductor. They can do this at any point of the electrical system. The user is then able to measure the current in the circuit without having to disconnect it.
Here is our list of the 8 best clamp meters we recommend to electricians:

What to Consider When Purchasing a Clamp Meter
When you’re considering buying a clamp meter, you should ensure you choose a clamp that gives very accurate results that are also repeatable. The meter should give a true-RMS reading so you know it’s accurate all the time, every time.
Ideal for your environment
A clamp meter needs to be ideal for your environment and it should not be for indoor use only. You should also make sure that your clamp does not need an operating range of at least 15 degrees Fahrenheit (-9 degrees Celsius).
When it comes to the issue of safety, there really should be no compromise. You should be able to use the meter when you’re wearing safety equipment, and it should also give the correct rating at all times. Ensure the clamp meter has the right category rating and comes from a brand that is reliable.
