How to Choose the Best Clamp Meters – Buyer’s Guide

Although there are great clamp meters on the market, identifying them could pose quite a challenge especially if your experience level is next to nothing. Also, there is a myriad of products on the market, therefore, selecting the best could pose quite a challenge as well.

Knowing just how important it is to get only the best, it is only expedient that you spend a bit more time making a decision.

This is because this decision would go on to determine whether you have a great experience or otherwise. In order to select perfectly, there are a number of factors which you would have to consider. These factors are essential to this selection process and they include the following:

Price

In most cases, the price usually comes first stemming from the fact that you would need to at least have some money in order to make any form of purchase. It is also possible that you might have a budget of sorts to help keep you in check or a spending limit.

This is one of the major factors that you need to take into consideration when making that purchase. Typically, clamp meters usually have some features in common, however, these features vary depending on the make and version that you are purchasing.

Clamp meters with better features usually have a relatively high price tag attached to them. Therefore, the amount of money you have to spend usually depends on the features that a clamp meter possesses.

Purpose of Purchase

Once you have decided that you need a clamp meter, you need to bear in mind exactly what you need it for. There are clamp meters suitable only for particular tasks. But there are others that work for all tasks.

However, purchasing one that is specifically designed to be used for the particular function that you have in mind is essential. For instance, a professional technician who deals with DC would definitely not go for a clamp meter that only measures AC.

In the same vein, if all you need a clamp meter for is the measurement of AC, then, you can literally go for anyone available on the market.

Features

Features go a long way in determining whether or not you purchase any tool, equipment or device. The features simply refer to the embedded characteristics that make a decision to perform a particular task.

For instance, in the case of clamp meters, a clamp meter that measures only AC is not in any way useful for a professional who deals with electronic circuits.

Similarly, features such as screen backlight, auto shut down, and data hold feature among others serve to make a clamp a lot easier to use and subsequently provides great value for the money that you spent on it.

Accuracy

This easily comes to the fore in terms of essential factors that you need to keep in mind. The essence of any measurement is to get an accurate value, therefore, a clamp meter that doesn’t give you this defeats its entire purpose irrespective of features that it might have.

It is essential that your meter gives a true RMS reading upon testing, this is, in fact, one of the first things that you should test for. Manufacturers usually detail the accuracy range of their clamp meters, therefore, you would need to go for one that has a very narrow margin of error.

Also, upon getting an accurate clamp meter, you might need to recalibrate after a while to make sure that it remains accurate.

Durability

More often than not, it is the materials that are used to make your clamp meter that goes on to determine just how durable it would turn out to be. Durability is an essential feature that a clamp meter should possess simply because you really have no idea when it could slip out of your hand.

It would, therefore, be heartbreaking for a clamp meter to fall to the ground and shatter or stop functioning. Especially when you just bought it. This is why you need to look beyond the features to ensure that the clamp meter that you are buying is highly durable.

Criteria We Used for Clamp Meters Review

The following are the criteria that we used in determining the best clamp meters on the market:

1. Price/Budget

Your budget goes a long way in determining the type of clamp meter that you end up with. That’s why it was basically the first criteria that we considered. Knowing that different people would definitely have different budgets, it was essential to include clamp meters that would easily fit into a wide range of budgets irrespective of limits.

In addition, we selected those whose price tags matched the quota of value that they had to offer to guarantee that you get maximum value for the money you would be spending.

This simply implies that we studied the features of each clamp meter and then decided whether or not it was actually worth the price tag attached. After doing this, we also made sure that there was at least one clamp meter that would fit into every single budget.

2. Reviews and Ratings

Reviews are simply the feedback that people give after making use of a particular product or service. This is why it is highly essential that reviews be taken very seriously. Reviews help to reveal flaws that the manufacturer would definitely not included in the product description.

This was why we made sure that we can out the major reviews that accompanied each clamp meter. And noted the number of people who complained about the same issue or claimed to experience the same problem.

After doing this, we had to drop a number of clamp meters off our list since they were clearly not living up to the alleged reputation.

3. Durability

Although these tools/equipment my pretty delicate and it is within the best interest of everyone that they do not drop, there is still a possibility that it might slip out of your hand sometime and take a pretty hard fall.

This is why clamp meters have to be made from very durable materials in order to guarantee that they would last long. Also, they should be made from materials that do not make them very dense.

This way, they would be easy to convey around without cases in the event that they actually have cases. When considering durability, you should also make sure that you check to see if it comes with a warranty.

Clamp meters that come with long warranties tend to have a higher likelihood of probability.

4. Ease of Use

Regardless of how any features a piece of equipment might possess, if it isn’t easy to use or operate, buyers would have a very hard time getting value for their money.

While selecting clamp meters based on the factors mentioned above, we also ensured that these clamp meters, despite the many amazing features that they might possibly be very easy to use.

This was done by looking out for features such as automatic shut down mode, backlit displays, automatic ranging feature, as well as high accuracy levels. All these features make decibel meters very easy to operate and guarantee great user experience.

Also, improved ease of use easily implies a higher level of accuracy in terms of readings gotten since the user would be highly proficient.

5. Features

This may be a late criterion that we used but it is certainly not the least. Features just about make up the very essence of your clamp meter. Features usually vary based on the type of clamp meter purchased and the grade, so to speak.

While clamp meters may possess the same features, it may be more advanced or developed in others. This is why knowing the purpose for which you need your clamp meter is essential.

While some tasks request certain specifications will regard to clamp meter features, others merely require possession of the most basic features that all clamp meters possess.


Conclusion

Clamp meters make up one of the must-have tools for any technician who deals with electrical installations/boards. This is why the selection process has to be very comprehensive. We know just how difficult it can be to select the best which is why we took our time to come up with this review and buyer’s guide. Following this guide, one certain guarantee is that you would definitely be getting the best on the market.
