all clamp meters are not created equal, therefore, it is very important that you buy a top-quality clamp meter that can provide precise results regardless of the environment that you will be working on the accuracy of the readings is one of the most important things that you should look at.

Preferably you should buy a clamp meter that records accurate RMS readings. If you do not do so, unnecessary electrical noise that light bulbs, as well as other devices, make can lead to inaccurate readings. Your digital clamp meter should also be able to meet the standard accuracy of 2% ± 5 counts. 

You should also look for a digital clamp meter that can work in any kind of environment. In case you use a digital clamp meter that is either under or over its definite operating temperatures, you will get inaccurate readings.

Lastly, you have to look at the features that the clamp meter you want to buy has. You should not go for ones that offer the most bonus features because they tend to be hard to use for their intended application.

Also, avoid digital clamp meters that have useless features like a tape measure. Alternatively, go for one that has the measurement qualities that you need so as to get the work done very quickly and also very correctly.


Are you within the electrical trade? If yes, then you know that you should have a clamp meter for solving electrical problems that might occur while working. As such, you should only use the best when it comes to clamping meters and the above list highlights the best clamp meters that you get on the market today.
