Kewtech KT1700 Single Pole Voltage Tester and Phase Finder
Add a clear first check for potentially live metalwork.
The Kewtech KT1700 is a single pole contact voltage tester and phase finder designed to provide an initial indication of AC voltage on metal enclosures and potentially live metalwork. With an operating range of 50–600 V AC, it combines a flashing red warning light with an audible tone when voltage above 50 V AC is detected.
Designed to remain functional while wearing full PPE, the KT1700 supports preliminary voltage checks before safe isolation. Its robust construction, IP54 ingress protection and probe tip conforming to HSE GS38 recommendations make it a practical addition to an electrician’s testing equipment.

Why Choose the Kewtech KT1700?
✓ Identify potential issues on metalwork early
The KT1700 provides an initial indication of voltage on conductive surfaces such as distribution board enclosures and water or earth bonding pipes. It can aid the investigation of PEN faults and diverted neutrals by drawing attention to potentially live metalwork before the safe-isolation process begins.
✓ Get straightforward feedback during initial checks
Separate red and blue indications communicate voltage detection and electronics status. The red flashing warning is accompanied by an audible tone, while the blue indication reports that the internal electronics are functioning. This gives the user clear information about what the tester is indicating.

❓ Frequently Asked Questions (FAQ)
Q1: What does the Kewtech KT1700 detect?
A. The KT1700 provides single pole contact indication of AC voltage within its 50–600 V operating range and supports live phase identification. Voltage greater than 50 V AC is indicated by a flashing red warning and an audible tone.
Q2: Can the KT1700 be used while wearing PPE?
A. Yes. Kewtech specifies that the KT1700 remains fully functional while the user is wearing full personal protective equipment.
Q3: What does the flashing blue LED mean?
A. A slow flashing blue LED with a single beep indicates that the KT1700’s internal electronics are working correctly. This is an electronics status indication.
Q4: Does the KT1700 replace safe isolation?
A. No. The KT1700 is intended to provide an initial indication of voltage before carrying out safe isolation. An absence of a voltage warning must not be treated as proof that a circuit is dead or safe to touch.
Q5: Which batteries does the Kewtech KT1700 use?
A. It uses 2 x LR6 AA alkaline batteries. Kewtech recommends replacing the batteries every two years based on Standard BS EN 61557 duty; this is a replacement recommendation, not a guaranteed continuous operating time.
