Best Clamp Meters 2021

Are you searching for the best clamp meters? If yes, then you are in the right place, as in this guide we aim to review the best clamp meters. Do well to go through this guide, to keep yourself informed on the best clamp meters, and then you can take a step further to purchase the one that suits you best.

A Clamp meter is an Electrical instrument used for measuring the current flowing through a conductor. An AC Clamp meter fundamentally comprises of a Current transformer in its jaws, bar CT generally. A Clamp meter utilizes the guideline of the current transformer to show Display Reading.

However, a DC clamp meter uses a Hall Effect sensor for the measurement of current.

Advantages of Clamp meter over other Electrical tools

There are mainly two advantages of Using a Clamp meter

  • Safety

In clamp meter, there is no need for physical contact between jaws and Conductors so it removes the old method of cutting into wires and measurement with the insertion of test lead into the circuit.

Due to the non-contact method, it provides safety to electricians.  This is the main reason why it becomes the most popular electrician tool for the measurement of current nowadays.

  • Convenience

It’s not necessary to shut down the circuit supply during measurement with a clamp meter, so it provides hassle-free measurement. So, it increases the Efficiency and Productivity of work.

Applications of Digital Clamp Meter:

A Digital Clamp Meter can be used to measure:

  • Current
  • Voltage
  • Crest Factor
  • Continuity
  • Resistance

CLAMP METER BUYER’S GUIDE

What to Look for in a Clamp Meter

Accuracy

Your clamp meter must offer consistent and accurate measurements. A dependable clamp meter puts out identical measurements for a single currency. You can rule out accuracy issues by opting for a model from a trusted brand.

Design

A clamp meter is a handheld device, just like floor jacks, and vernier calipers. As such, it should be portable, durable, and easy to use. We recommend opting for a meter with a glowing LCD screen and distinct controls.

Ensure that the device is durable enough to withstand a few bumps and bruises. Always opt for a model that works well in both dim and bright conditions, though not as bright as handheld spotlights. You might be testing a wire in a vehicle or a crawlspace. Where ever your electrical work takes you, you want to be well-prepared.

Safety

You’ll be dealing in high-risk situations. Remember, a clamp meter is a tool for assistance, and assistance only. Never compromise on your safety. You should be as careful as you are with a saw horse

Since you’ll be dealing with circuitry and high voltages, ensure that your equipment is adequately insulated at the holding points.

Features

Unlike refrigerant scales, Some clamp meters offer an assortment of data tools, such as auto-ranging, holds, and sleep functions. Auto-ranging features enable users to receive automatic readouts. This is extremely helpful if you do not know the resistance range of the current you are testing.

Instead of flipping through several settings, you can simply set your clamp meter to its auto-ranging setting. Data holds are also helpful. They enable you to store and compare measurements.

A meter that can store more than one measurement is extremely desirable. Of course, auto-shutoff and sleep functions enable you to conserve battery power without making a conscious effort to do so.

Measurement Parameters

Most clamp meters provide you with a measurement of AC currents, which is different from that gottten when soldering. However, some meters also offer AC/DC voltage readings. On top of that, some clamp meters provide continuity, resistance, capacitance, and diode measurements or reports.

Continuity readings determine whether a current is complete and connected. Resistance measures how electric current flows through a device. It is reported in ohms. Meanwhile, a diode is a device that keeps currents flowing in one direction.

Detailed readings provide users with a more in-depth understanding of electric currents. This makes for safer, more accurate repairs.

Quality

To make it your buddy for a long period, look at its build quality. It should be heavy-duty plastic with tough construction and necessary ruggedness. Some of the best clamp meters have also rubber toppings that make their hold easy.

Proper certifications

A good electrical device always comes with a safety feature as its priority. Here I am referring to proper lab tests and certifications. The common certifications that you can look for are CE, IEC, etc.

However, there are many more authorized certifications or rankings that claim the better performance and safety of the device.

Meter ratings

Make sure to look for the current measurements. They are necessary and indicates what you are looking for. So, consider the maximum voltage or current holding of a clamp meter. This is because using clamp meter other than its intended ratings can cause harm to the electrical equipment as well as the user.

For instance, if you are an electrical guy and looking to use clamp meter for industrial purposes, then see its suitable use and maximum meter ratings. On the other hand, see the suitable use in case of residential purposes. If you are specifically looking for home use then go for Amprobe AMP-210 ELSA2A.

Environment

Your clamp meter should be suitable to work in all types of environmental conditions. A clamp meter has to work usually in different environments, unlike digital multi-meter. Thus, it should be capable of withstanding various temperatures.

This is why some of the clamp meters come with temperature reading functions. However, you should particularly look for the temperature tolerance features before buying a clamp meter. This would help you to purchase specific clamp meters for high temperatures.
