Megger LTW 425
The new Megger LTW425 Loop Impedance Tester is a time saving loop tester that eliminates the risk of incorrect connections. It uses two wire earth loop testers to verify the loop impedance of a live electrical circuit without the need to disconnect the electrical supply. The dependable two wire testing of the LTW425 is a major benefit in applications where the neutral is missing or inaccessible, such as light switches and systems with 110V centre-tapped supplies. This loop impedance tester provides all of the facilities necessary for two wire, non-trip loop testing on all supplies between 50V and 440V AC. As with all of the LTW300 series, the two wire loop testing solution is guaranteed not to trip 30mA RCDs.
Megger Loop Impedance Testers use the latest digital processing techniques to separate the test signal from the fundamental frequency of the supply. This means the Megger LTW425 Loop Impedance Tester automatically averages a large number of results over the duration of the test, enabling non trip testing to be performed without DC injection. PFC calculation is provided as standard with all Megger Loop Testers. These tough, easy-to-use instruments have been developed, after extensive customer research, specifically to address the needs of electrical contractors working in today’s demanding and competitive market conditions.
The LTW425 offers a high current, high resolution loop test to three decimal places. This is ideal for the correct Ze on a supply, particularly on PME installations and allows for a greater accuracy of results.

Megger designs and manufactures portable electrical test equipment. Megger products help you install, improve efficiency, reduce cost and extend the life of your or your customers’ electrical assets.
Established in the late 1800s, the company has been designing and making test and measurement instruments that perform electrical measurements for preventative maintenance, troubleshooting and commissioning for decades. Megger products have supported customers all over the world to improve their facilities’ efficiency, reduce costs, extend the life of apparatus and through trending and analysis, anticipate equipment failure and future performance. It now has local offices in many locations with technical support teams and distributors all over the world. Manufacturing plants are located in Germany, Sweden, the UK, and USA.
Working with customers
Megger believes that by working closely with customers it can deliver the best customer solutions and after-sales service today, and in the future. Megger is committed to anticipating client needs by listening to customers and industry specialists while continually investing in innovative research and development, design engineering and manufacturing techniques.
Our strategy is to produce all our products with a single brand name, Megger. The advantages to you are that you know the products and software will work well together, and all the products have a similar yet distinctive ‘look and feel’ with their dark and light grey casings. We don’t waste colour on trying to make our test instruments pretty – we reserve it for useful functions such as range selectors and displays. Our design engineers come from many different nations, and they regularly exchange ideas and tips with colleagues from other countries. That means you get the latest innovations, one of the reasons that Megger products are so advanced. As more companies join the Megger family, you may find some test equipment sold by us that have not yet transitioned to the Megger identity system. Don’t worry – our top priority is ensuring that product quality is right. We’ll get round to making sure the colours are the same later.
How the greatest brands in test and measurement came together
Our systems are geared to keeping things local – localised engineering, localised marketing, localised decision-making. Our employees are proud of the companies and brands that go to make our company history and many of these names are still trademarks or registered trademarks of the company in many countries.
Delivery & Collection Information
We use next day couriers to deliver all our test instruments. That means it doesn’t matter if you’re 2 or 200 miles away, we can have the test equipment you need, delivered first thing, next day.
When you have finished with the test equipment we can arrange for the same courier to collect it from you.
We also offer a same day delivery service for when you really need the test equipment urgently.
