A professional-grade, IP65-rated voltage tester featuring 3-phase rotation indication, continuity buzzer, and single-lead live detection.
Engineered for the UK Trade
The ATUTEN UT15C is more than just a voltage indicator; it is a comprehensive testing solution for the modern UK electrician. Designed to fit seamlessly into a GS38-compliant safe isolation procedure, it provides clear, unambiguous LED readings from 12V to 690V. Whether you are working on a domestic consumer unit or a commercial 3-phase distribution board, the UT15C delivers the confidence you need to prove dead.
Versatile 3-Phase Functionality
Unlike basic testers, the UT15C includes built-in phase rotation testing. This allows you to quickly determine the sequence of phases in a 3-phase system without reaching for a separate meter. The slender probe design and integrated LED torch make it ideal for use in deep or dimly lit enclosures, ensuring you can see exactly where you are probing every time.
Durability Meets Safety
With an IP65 rating, the UT15C is dust-tight and protected against water jets, making it suitable for both indoor and outdoor site work. The ruggedised body is built to withstand the inevitable drops and knocks of a busy toolkit. It also features a single-lead 'Live' test (Zero Line/Fire Line identification) and a continuity buzzer for fast circuit tracing and fault finding.

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.
Kieran O'Sullivan, Birmingham
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.
Arjun Singh, Leicester
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.
Gareth Evans, Cardiff
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.
Siobhan Murphy, Glasgow
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.
David Miller, Leeds
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.
Mark Thompson, London
