Kewtech レビュー 

Have had my KT66DL for over 12 months now and absolutely love it!
I was unsure on what Multi-Meter I wanted and to make sure I got the correct one I phoned the team, explained my requirements and they told me to check out this model. Great service from the team, quality product with some really useful accessories and the prong with the test button on it is an absolute game changer! Usually the envy of the team and since having mine 3 others have converted from other brands.

I’m so happy with my new Kewtech KT66 DL! I upgraded from a 1721 tester, so it was a big change moving to a different brand, but it’s honestly one of the best decisions I’ve made.

The KT66 DL is incredibly user-friendly and very easy to navigate, while still offering so many features. It makes testing quicker and more straightforward, and the build quality is excellent.

If you’re looking for a new multifunction tester (MFT), I 100% recommend the Kewtech KT66 DL. It’s been fantastic to use, and I couldn’t be happier with it.

⭐⭐⭐⭐⭐

Love kewtech gear. Its accurate and robust.
There are support videos online that help you to know how to correctly use the equipment and with my multi function tester the help button helps when you have those blank moments on what to test. But ultimately I love using this gear over the megger

Kewtech is one of the best testers I’ve used I learnt on them and will never tuen back easy to use and understand the best testers out there.

Kewtech KT66- absolutely phenomenal bit of kit, I've added to this with some accessories, socket tester, current meter and volt pen. Wouldn't use another brand for testing equipment. Kewtech loyal 🫶

Bought the KT66DL a few months back at I’d never look back. About half the price of a megger or fluke but does it all and more. Auto null feature is a game changer and user interface is a breeze, recommending them to everyone I speak to now.

Really impressed with Kewtech products. Easy to use, reliable, and good quality. The equipment never lets me down, works great and makes testing straightforward. Definitely recommend to anyone looking for dependable testing tools. Top testing tools for Electricians 👌

I've used the Kewtech KT66DL for over 2 years now after using a variety of other testers on the market, and can say theirs has been my favourite one by far. Very sturdy versatile bit of kit, easy to use and just overall nice to use. The testing settings are all very in depth and easy to navigate around with multiple options for various sub settings to test to/ with within each test function.
Highly recommend if you are looking for a good reliable tester with great quality

Been using Kewtech testers KEWEVSE, KT63+ and their plug-in testers/probes and I honestly wouldn’t use anything else.

Reliable, easy to use, and spot on every time. Proper solid kit that just does the job.

Well built, reliable & accurate MFT's! If you're just starting up or a time served spark fed up of other brands that constantly have issues then a Kewtech is for you!

Great value for money, excellent customer service & a fantastic range of accessories to make your testing job more efficient!

I started 20 years ago with Fluke 1652, then I had a Megger 1552, then I had a Kewtech KT65, then I had a Megger 1721, then Chauvinarnoux.

I've got a fair amount of testing & MFT experience & after using all these MFT's I feel like I've come back home to what I think is a simple, honest & proper MFT that's suitable for all sparks.

Kewtech have definitely changed since I last had one, increased capabilities, aesthetics & reliability.

I've met a few members of the Kewtech team and they are all honest, knowledgeable & easy to approach when you have any questions.

One of them also does a fantastic Taylor Swift impression!

I've had my KT64DL for 5 years now and everything about it is great. It's easy to use, accessories have a much better lifespan than most equipment I've used. 100% would recommend to anyone wanting to get an MFT.

I’ve been using kewtech since I started out. All their kit is great and made for ease it does actually what you need it to with no hassle, everything is set out perfectly. Very reliable

Been using kewtech MFTs and accessories for around 7 years now and im never changing. Started out with the kt63 for domestic which I couldnt believe the consistency in regards the continuity setting. I previously used company MFTs but always had kewtech leads no matter the brand. Once I parted with the 63 I had a 63plus which was amazing too but couldn't resist the temptation and bought a KT66DL in 2022 and I couldnt be happier with it. 4 colleagues have used it and purchased one for themselves. The fact it has kewtechs original reliable attributes such as continuity accuracy and impedance consistency now with exceptional 2 lead loop tests and ev setting for RCDs was the definitive reasons made me happily hand over my cash for it...and I dont regret a single penny. In addition to the MFT I also bought a KT300DL to keep in the tool bag for fault finding and have most accessories. Kewtech are leaders for innovation when it comes to the adaptors, light mates, kewlok kit and many more. Great equipment all around and the most helpful customer services who are quick to reply and very accommodating

I’ve used Kewtech for well over 10 years, their products are second to none as is their customer service. Wouldn’t use any other brand for my testers

The best testing equipment on the market, ideal for any professional in the business

I’ve been using the kewtech Ezypat for a number of years. Very user friendly perfect for smaller PAT testing jobs. I would have another without doubt and recommend the tester to others.

Excellent electrical testing manufacturer , been using there products for 10+ years great easy to use testers and supportive customer service

Fantastic equipment. My KT66DL could be run over by a bus and I’m pretty sure it’d still work accurately.

By far the best electrical testing suppliers out there.

I recently made the switch to Kewtech from owning a Megger MFT. Having undertaken and passed my 2391-52 back in 2022, I then made my first MFT acquisition, which was a 2020 Megger 1741+. It was 3 years old at this point, and I bought it on the back of using a Megger on my 2391 course and on recommendation from my lecturer.

The Megger did what it said on the tin. It tested and that was all that was needed. But as time went on, my needs became more complex, and I began to notice it was becoming unreliable. It started with the leads. They're terrible! I was replacing them every 6–8 months and the readings became erratic. It then progressed to failing calibration on 3-LO and finally with an Err27 message on the test instrument.

In between all of this, I had already acquired some Kewtech accessories and equipment on the back of some Instagram posts. The light adaptors, the jumper cables and the PAT adaptor. Around Nov of 2025, I was already considering moving to Kewtech as reliability was becoming an issue with the Megger. I decided to buy Kewtech leads instead of Megger's, which are still used with my new MFT and are still very accurate.

The Kewtech accessories and equipment I already owned. I was quite happy with it, they did what they were meant to do.

Around the new year in 2026, I noticed Lawrence (Bristol Sparky) had moved across to the KT66DL and was making content on how accurate and reliable the Kewtech was.

So one Saturday evening in late January during a planned weekend shutdown of a mechanics garage for a rewire, the Megger threw up an Err27 message while testing the installed circuits. Megger upon enquiry, the following week, they wanted £400 to repair it.

It was gone for 6 weeks for repair with a different calibration company at the cost of £65. It also left me without an MFT to finish the garage and get it certified for insurance purposes. At the point of that outrageous quote, my relationship with Megger was over. The MFT had become a liability, as did my services as an electrician.

I had to borrow an MFT to complete the rewire of the garage, and in short, I felt like a mug and I felt like I'd let my customer down.

I subsequently purchased a KT66DL on the content that Lawrence had posted on Instagram and I haven't looked back. My confidence in assuring any works I undertake has been restored. The MFT goes above and beyond everything I need; the leads feel of considerably better quality, it tests SPDs, it does PAT, it even has a noise reading capability on Loop.

Megger absolutely shattered my confidence in testing & reliability and Kewtech have swept it up and rebuilt it. I absolutely hate letting customers down, and on this occasion my customer had to go and ask his insurance company for more time to complete the work.

OK, granted, I should've had a backup MFT for scenarios like such. I just didn't expect it to happen with a top line MFT like the 1741+ in such a short space of time. Based on other content from ALO Electrical & Security, my backup MFT will be the solid Kewtech KT63, when I eventually do purchase one.

In all, I'm delighted with the purchase. As much as I've tried to make this a positive review of my Kewtech MFT and less a moan about Megger, I've tried to give some background on what prompted the move and the surrounding experience, but that said, if you have been let down by your own MFT, make the swap.

You'll not regret it.

Also, credit where it's due, Kewtech are also very responsive and very active on social media and are always available to answer questions when required or to have a general chat with them.

Long may it continue!
