The 10 Best Clamp Meters Reviews and Buying Guide 2021

The 10 Best Clamp Meters Reviews and Buying Guide

Electrical professionals understand how important a clamp meter is in their daily activities. These electrical instruments will help measure the current flow in a conductor without direct contact. Given how important this tool is, you can’t take any chances on its quality and there should be no compromise on choosing the best clamp meter. In this article, we will list some of the best digital clamp meters here and have compiled this list based on some key factors.

Safety: Safety is the highest and top factor that you need to check with a clamp meter. Since the entire point of a clamp meter removes physical contact between the hand and the conductor, ensure the clamp meter in question has the highest safety rating.

Convenience: The convenience of a clamp meter involves the smartphone’s adjustment, the size of the screen, and other factors that can improve the ease of use of the clamp meter—the better your choice.

Clamp Size: The third key factor you should consider is clamp size. Larger in clamp size, you can measure the conductor. Clamp sizes vary from 17mm to 45mm and your choice depends on how big your conductor is in your workplace.

In addition to these three factors, you can consider a few more factors when buying a clamp meter. We’ve included them all in the purchased guide section of the article. Be sure to check it out too. Now without further ado, let us jump in and review the best digital clamp meters.

Buying Guide: How To Pick The Best Clamp Meter

Clamp meters are electrical instruments that can measure the current flow in a conductor. These devices improve protection from the conventional method of measuring current flow (which is cutting a live wire and measuring current flow by inserting a test lead over the circuit). Due to the hazards associated with this procedure, a clamp meter was introduced. A clamp meter uses the principle of current transformer. The clamp of the clamp meter captures the magnetic flux and measures it and then shows you the reading of the current on a screen.

Basically, there are two types of clamp meters

  1. AC Clamp Meter

These devices are typically used to measure AC current

2.  DC Clamp Meter

Multipurpose devices that can measure both DC current and AC current.

A DC clamp meter mostly uses an effect sensor for accurate measurement of current. In this purchase guide, we are going to list a few important things you may want to consider before buying a clamp meter.
