Buying Guide

Your electric instrument box demands the best measuring tool for accurate and precise voltage, current, and resistance measurements. So buying a clamp meter for this purpose is just incredible. Although, before this, you have to keep several essential factors in your mind. Hence, this buying guide will help find the best measuring tool by explaining clamp meter features briefly.


Clamp size is the foremost factor to consider while buying the clamp meter. It refers to the opening ends of the tool; these ends are actual holders. Typically, devices with 17 mm to 45 mm opening ranges are present. You have to choose according to your conductor size. Always select that which is large enough to hold large conductors easily without touching your hands.


Secondly, the maximum resistance limit of the clamp meter is necessary. Both with a minimum of four Kilo Ohms and with high ten kilo-ohms meters come that are suitable for local usage. However, if you measure heavy conduction instruments’ voltages or capacitance, choose a high resistance clamp meter as 20 Kilo-ohms.


The backlit screen factor should consider if you will work in dark areas because it becomes difficult to see screen readings clearly with a backlight screen in these areas. Further, the backlit feature makes conduction easier.


Last but not least is the True RMS feature; it is necessary and the central part of the best clam meter. Only this feature will give you accurate readings that can measure linear and non-linear loads regardless of distortion. So before buying, check out whether a clamp meter holds this or not because, without this, proper calibration not measurable, and the results will lead to error.


In the end, All above are the best clamp meters for 2020 and are of high quality. And we reviewed clamp meters that hold extraordinary features such as RMS conversions, durability, easy to operate, backlight feature, and many others. Secondly, all reviewed tools are affordable so that you can choose freely for home-usage and Fluke 323 Clamp meter is recommonded.
