How To Choose The Best Cable Network Tester

We have shown you multiple types of network cable testers. Each of them has its own features different from others or there are testers who have the same features but vary on price.

Thus, you get confused about what you should buy and what you should not, here comes the role of this buying guide. It will tell you what are the features that can make your testing right and serves your purpose.

Just go through the points that we have described below, and select what suits you best and choose from the brands mentioned that are right for you.

1. Compatibility with cable 

Cable network testers are designed in such a way that they support a particular type of cable. Hence it becomes very important for you to lay focus on what type of cables you have in your networking panel.

Once figured out what cables you have, just compare all the testers in the given price range and find which tester supports all the cable you need to test. But this will be the case if you are using it for home purpose only.

If you are a professional network technician you need to get a network tester that supports nearly all or most of the cables. Because when you will go out for testing you will find different kind of tables at different workplaces.

The most common cable that exists is coaxial cable hence it should always be included in your tester. Other than that, the testers we have mentioned here support multiple kinds of cable you can select anyone from these as per your need.

2. Type of testing 

Network tester carries out multiple testing in your cable network. But what specific purposes they can perform is very important to figure out. Because, if the test that you want to carry it in your network is not provided by your tester then there is no need of buying that.

The different tests that a network tester may perform are continuity check, voltage check, measuring the length of cable, pin testing, checking the proper connection, finding the port location of cable and many more.

Based on what kind of testing you want to carry out, select the one that serves your purpose. If you are a professional technician find the tester that supports multiple kind of testings.

The testers that we have mentioned here are suitable for both home use and professional technicians. Select the one from this article that you find most suitable for you.

You should also focus on the accuracy of results as there will be trouble if you are not getting accuracy in your results.

3. LED/LCD Display on tester 

Based on testing that your tester offers it may have a display screen to show your result if it is a numerical value. But there are testers that don’t come with a display screen as such tester only show you the results in form of sound or light indicators like continuity testing, pin testing etc.

However, our advice for you will be to go for the tester that comes with a display screen. As you may miss the sound in a noisy environment or light may not glow up due to some reasons, but the screen will always show you the results.

Hence, if you are a professional technician who will need to measure the voltage of the cable line or length of cable then you will need to have a display type tester.

We have both kinds of tester in our list display as well as non-display select the one which suits you best. Also, the price of non-display testers is very less than the display type.

4. Length of cable that can be measured 

One of the testing that the network tester does is measuring the length of the cable without you actually moving through the entire length of cable. So it becomes important for you to note what maximum length of cable your tester can measure.

The brands we have mentioned here can test from 300m to 1Km length of cable in just 3-5seconds.

But most of the cables in network use are not above 300m hence maximum testers that we have included in our list have the range of 300m. This reduces there price also because unnecessarily going for long length testing cable tester will make them expensive which is not needed at all.

5. LED indicators and Sound Speaker 

These two features are must-have in your tester features list. Whenever you carry out your testing you get notified by light indicator or speaker or sometimes both together that testing is done now check the result.

This ensures that you don’t miss the reading and get accurate result always and at correct timing. All the brands that we have mentioned here are equipped with both these features.

6. Warranty 

Having a warranty of your product ensures that you don’t have to bother much if the device malfunctions you just need to inform the company and your issue will be rectified without any fees till the time it is in warranty.

Network testers being electronic device are most prone to malfunctioning if used in extreme conditions like excessive heat or cold hence you should always check how much warranty your brand is providing on your tester.

7. Price 

With price comes more features and better durability in your product. It is worthy to spend more on your tester when it comes to the durability of that as it will make it run longer and save your money to be spent in repairing of your tester.

But unnecessarily spending on features that you don’t require in your tester is a waste of your money.

Price of your tester is based on the testing it can carry out, types of cable it supports and other aspects. Find your aspect and choose then which is most economical to you.


So now you are all aware of the brands that you can buy for your cable testing issues. What we will advise you, is just go through your needs and price you can pay, you will end up selecting the best choice for you. This article makes your this task easy and this is what our purpose was behind this article.

But the one brand which impressed us most and what we want to recommend you is Southwire Tools & Equipment M300P Network Cable Tester. You can easily use this tester in dark light. It is able to absorb every shock that makes it durable. It also protects all the cables from dust as it carries port sheets.
