The KT65DL multifunction tester is a robust instrument, which combines the latest anti-trip technology, advanced memory, phase rotation and earth resistance. It’s easy to use and a reasonably priced piece of testing equipment, which now comes with high quality G7 test leads.

Most important to note, the KT65DL tester works to the BS 7671 18th Edition Wiring Regulations, as the test current exceeds the 200mA required. The KT65DL comes with multiple selectable voltages – 250V, 500V and 1000V.

The padded neck strap makes it comfortable for long periods of use and easy to carry around, while the case has enough room in to fit other testing equipment. Our head trainer explains the benefits of buying a Kewtech product, as “they have excellent technical support, fixed price repair policy and even in-house calibration service.”

However, as with every product, there are some drawbacks, one of which being the small display, especially when it comes to RCD testing. “It’s slow doing earth fault loop impedance test L to PE and it’s a bit susceptible to transient noise with a fluctuation to magnetic fields” explains our head trainer further.

The test lock button is a great feature and the leads and accessories are good to replace. Our head trainer also says, even though he has a Fluke and a Megger, he would still give it 4 out of 5 stars and calls it “the best on the market for durability and price”.
