Best Network Cable Tester Buying Guide

Network or ethernet cable testers come in different sizes and shapes. They also have varying capabilities, making it challenging to decide. Fortunately, we have included this buying guide to help you know what to look for when buying a network cable tester.

Consider the following factors for the best decision-making:

1. Length Testing Capability

Some network cable testers can test cables up to 2,000 feet long, while others can only get up to 1,000 feet. This is a primary factor if you already know the size of the network. You don’t want to be limited by the range of your tool.

2. Build Quality

Work environments are often associated with harsh conditions or occasional droppings. You want a ruggedly built network cable tester that will withstand such situations and last long. Think of it as a long-term investment because you don’t want to get to the market looking for what you just purchased a few months ago.

3. Cable Compatibility

A multipurpose cable tester would be a great fit because it works with all cable types. But if the budget is tight, look for what is compatible with the network cables you will be testing. You don’t want to buy what you can’t use when you get to the workplace.

4. Cabe Testing Capability

Ask yourself why you need a network cable tester and what you want to test with it. You may want to perform a voltage check, continuity check, able length measurement, pin testing, port location, or any other. The tool you buy should have that capability. Otherwise, you will return to the market sooner than you thought.

5. User Interface and Ease of Use

Network cable testers with LCD screens are the best choice because they show test results more accurately, but they come at a high price. If you opt for more affordable options, it should have a friendly user interface and unambiguous means of showing the test results. In many cases, they have LED indicators. Ensure these are readable and you can interpret results.

6. Other Factors

Other factors that make any network cable tester great include accuracy, portability, connectivity, and battery life. For instance, you don’t want a tool whose battery cannot power it for a whole day. Similarly, trusting the test results is impossible if using an inaccurate cable tester.


What are the types of cable testers?

Network cable testers are grouped according to their CAT ratings. The different types include CAT 3, CAT 4, and CAT6, but you can also find subcategories for coaxial, triaxial, and twisted pair testers.

What are the different types of cables used in networks?

Different cables are designed for various applications, but the most common ones used in networks include the following:

  • Unshielded Twisted Pair (UTP) Cable
  • Shielded Twisted Pair (STP) Cable
  • Cable Installation Guides
  • Wireless LANs
  • Unshielded Twisted Pair (UTP) Cable
  • Coaxial Cable
  • Fiber Optic Cable

When would you use a network cable tester?

As the name suggests, network cables are tested using a tester. You use this tool to determine whether or not the network cables will work when connected. You can also use it when finding a break in the insulation or other faults in a network. However, high-end network cable testers can be used for other purposes.

What is the purpose of testing and inspecting the network?

Testing a network provides an objective, independent view of the network to allow stakeholders to understand and appreciate the risks of the network. It also offers information about the quality of the products and services being tested.


Network cable testers are a must-have for any technician in networking or quality inspectors. You can make the best decision with this product review and buying guide. But the following are our recommendations:

Fluke Networks MS2-100 MicroScanner2 checks all boxes regarding the feature, capability, and design. If you have the budget, it is the best option. This reliable tool will serve you for decades while meeting all your needs.

Klein Tools VDV501-851 is the second choice, and we recommend it if the first option is expensive or if you want a user-friendly network cable tester. It is compatible with all cable types and can analyze cables as long as 2,000 feet. This tool is also reliable and durable.

The last option is the most affordable tool you can get. Klein Tools VDV526-100 is easy to use and detects most faults on many network cable types. It also has a long-lasting battery, capable of powering the device for up to 80 hours when active.

You can also use our buying guide to find other options for your application. Generally, network cable testers reviewed here are reliable tools.
