10 Best ESR Meters Reviews in 2021


Those of you who work on electronics projects and devices quite often will know that it is highly important to ensure that you are using the right components while soldering. This can include components like capacitors, transistors, resistors, diodes, and various others. And while there are various ways to test these, you can consider using one of the best ESR meters given down below since it is perfect for checking small resistance values due to these features:

  • Display: Since an ESR meter is a digital testing device, all of them use a digital display for showing you the readings. And to ensure that you can see detailed readings properly, almost all of them come with LCD displays except for a few budget options which may feature an LED display itself.
  • Identification: As an ESR meter can be used to test a wide range of electrical components, changing the testing mode again and again can be quite frustrating. Due to this, many ESR meters come with an automatic identification function that automatically changes the testing mode according to the electrical component being currently used.
  • Measurement Range: Because you will be testing all kinds of components, their measurement values may or may not come within the supported measurement range of your ESR meter. Hence, you should go with an ESR meter that offers as large of a range as possible for all of its testing modes like resistance, capacitance, inductance, and others.

While these are some of the most important features regarding ESR meters, these meters have much more to offer. Therefore, all the best ESR meters given here also have their major details and factors explained properly along with a complete Buying Guide which should be handy for you when it comes to picking the best ESR meters by the end of this article.

Buying Guide for the Best ESR Meters

Similar to many other electronics testing tools, an ESR meter can also be used for various applications and uses. Whether you want to test the resistance of components, switches, PCBs, or anything else, these can be great options.

As you can even test for short circuits with an ESR meter, we have already given some of the best ESR meters earlier in this listicle. With all of these ESR meters, you can also come across their important specifications and features which can be handy for picking the right one for you. Although, if you are still confused, consider checking this extensive buying guide for the best ESR meters:

1. Display

While it does not affect the performance of your ESR meter, its display can certainly affect the overall user experience. This is due to the reason that all of the readings that you are going to take with your ESR meter will be checked using its display. To ensure that you can easily and properly read all of the readings being shown by your ESR meter, most of them use an LCD display. Some of these may also include a backlit LCD display for easily seeing the readings even in the dark. Although, if you are going for budget-oriented ESR meters, then they may have an LED display instead.

2. Identification

One of the best things about an ESR meter is that it can be used for testing all kinds of electrical components. This includes components like resistors, capacitors, inductors, diodes, triodes, MOSFETS, and much more. For testing any one of these electrical components, you can simply select the testing mode corresponding to it. However, changing the testing mode again and again can be quite frustrating if you are working on a large electrical circuit. Due to this, almost all ESR meters available out there come with the support for automatic identification. This allows the ESR meter to automatically change the testing mode as you are testing your desired electrical components.

3. Measurement Range

Since you will be using your ESR meter for testing different kinds of electrical components, you will need to use a different measurement range for each one of them. Even if you are working on just resistors for a certain electrical project, different resistors may have completely different resistance values.

Due to this, it is highly recommended to go with an ESR meter which offers a large measurement range for easily and properly testing all kinds of electrical components. You need to make sure that not only does your ESR meter offer multiple measurement ranges, but all of these measurement ranges are also as large as possible for both small scale and large scale applications.

4. Testing Compatibility

As mentioned earlier, almost all ESR meters allow you to test a wide range of electrical components for high versatility. Although, not all ESR meters are going to be the same since not all ESR meters will be able to test the same number and types of electrical components.

Hence, checking the testing compatibility of your ESR meter in terms of the electrical components you can test with it is highly important. Some of the common electrical components which can be tested with ESR meters without any compatibility issues include options like resistors, capacitors, inductors, diodes, triodes, MOSFETS, and others where any ESR meter which supports as many of these as possible will be highly versatile.

5. Automatic Power Off

When you are working on large-sized electrical circuits, then it is highly likely that you are going to spend a long time on the same. Because of this, the 9V battery of your ESR meter may run out if your ESR meter is left turned on. Thankfully, you will not have to manually turn off your ESR meter in most cases. This is due to the reason that a lot of them come with an automatic power off function which turns off your ESR meter when you are not using it. Such a function will turn off your ESR meter after a certain period of time like 20 seconds or 30 seconds if you have not used any of its functions.

6. Warranty

Even though not all ESR meters available out there may feature a warranty, going with an ESR meter that offers the same is still highly important. This is due to the reason that any ESR meter which offers a long warranty period is going to be quite ideal for long term usage and your peace of mind. In general, any ESR meter which includes a 1-year warranty will last longer than options that may offer a 30-day warranty or even no warranty period at all. You should also check the build quality of your ESR meter since some of the barebones options come with an enclosure which might not be the most durable option made for long term usage.

FAQs for the Best ESR Meters

1. Can you properly see the LCD display of an ESR meter in the dark?

While it is not true for all ESR meters available out there, some of them come with backlit LCD displays. Such displays light up in the dark so that you can properly view all your readings and properly test circuits.

2. How does an ESR meter automatically detect electrical components?

In order to automatically check and identify the component being tested, an ESR meter sends multiple voltage signals to test them and compare them to its internal data to successfully identify the electrical component that you are currently testing.

3. How do you test a circuit with an ESR meter?

Similar to a multimeter or any other digital testing device made for electrical circuits, an ESR meter also uses red and black probes which come with fairly long cables so that you can test each and every component of your circuit with ease.

Conclusion

Just per the name, an ESR meter or an equivalent series resistance meter allows you to check the resistance of multiple components connected within a single circuit. Being digital testing equipment, they even offer more functions to the user for practicality and ease of use. Thus, we have already given a few of the best ESR meters up above in this listicle.

To help you in picking the perfect ESR meter for your needs and usage, all of these ESR meters have been given along with their significant aspects and factors alongside a detailed buying guide.
