ATUTEN UK
A professional-grade, IP65-rated voltage tester featuring 3-phase rotation indication, continuity buzzer, and single-lead live detection.
How to Use
- Verify the tester is working correctly by using a known live source or a proving unit.
- For voltage testing, apply both probes to the circuit; the LED bargraph will illuminate to show the voltage level.
- For phase rotation, follow the L/R LED indicators when connected to a 3-phase supply.
- For continuity, ensure the circuit is dead, then apply probes; the buzzer will sound if resistance is low.
- Always re-verify the tester on a proving unit after testing to confirm a 'dead' reading is accurate.
What Our Customers Say
Solid bit of kit. I use it daily for safe isolation. The phase rotation feature saved me carrying a second meter on a recent industrial board upgrade.
The LED display is very bright, which is great because I'm often working in dark plant rooms. Much more robust than my old Fluke which cracked after one drop.
Great tester for the price. The leads are nice and flexible even in cold weather. Only wish it came with a belt holster, but otherwise perfect.
The single-pole live test is surprisingly handy for a quick check at a switch. Feels very sturdy in the hand and fits the GS38 requirements perfectly.
Ordered on Tuesday, arrived Wednesday morning. Used it straight away for a boiler install. The continuity buzzer is loud enough to hear over a running pump.
Good value for money. It's my go-to for domestic EICRs now. The probes are slim enough to get into the back of most sockets without fuss.

At ATUTEN UK, we understand that for a UK electrician, a voltage tester isn't just a tool—it's the primary line of defence in safe isolation procedures. Our mission is to provide the trade with robust, reliable, and GS38-compliant testing equipment that stands up to the demands of site work, from busy consumer unit upgrades to complex three-phase industrial installs.
We have built our reputation on the UT15C series, focusing on a no-nonsense design that prioritises clear, at-a-glance LED indicators over fragile digital screens. Every piece of equipment we supply is engineered to handle the 'real world' of UK electrical contracting, where low light, tight spaces, and the need for speed must never compromise safety.
Based in the UK, we support our customers with local technical expertise and a commitment to safe working practices. We don't just sell testers; we advocate for the full safe isolation workflow—lock off, prove, test, and re-prove—ensuring every sparky goes home safe at the end of the shift.
