Testo 745 Non-Contact Voltage Tester
£32.25 (Inc. VAT)
The Testo 745 Non-Contact Voltage Tester is a professional-grade AC voltage detector designed for fast, safe, and reliable voltage checks up to 1000V, featuring dual sensitivity levels, IP67 protection, and high-frequency interference filtering for accurate fault detection.
The Testo 745 is a non-contact voltage tester (NCV) built for quick and safe detection of AC voltage without direct contact. It measures from 12V to 1000V AC and provides clear visual (LED) and audible alerts, allowing electricians and technicians to instantly identify live circuits and fault sources.
What sets the Testo 745 apart is its low-pass filter technology, which minimises false readings caused by high-frequency interference—common in modern electrical environments. With two adjustable sensitivity levels, built-in torch, and rugged IP67 waterproof and dustproof housing, it is ideal for professional use in demanding conditions.
