Tenma Tone and Probe Tester Kit

The Tenma Tone and Probe Tester Kit is an essential diagnostic tool for electricians, telecoms engineers, and IT technicians, enabling the safe and efficient identification and tracing of wires or cables within a group without damaging their insulation. This versatile kit is designed to simplify complex tasks such as fault-finding in telephony systems, checking cable continuity, and locating break points in wiring runs.

Its core function allows you to send either a single solid tone or a dual alternating tone down a wire via the handheld transmitter. The matching receiver can then accurately trace this signal, helping you to identify the correct cable amongst a bundle, follow its path through walls or conduits, and pinpoint faults. For telecoms work, it can also identify the state of working telephone lines, distinguishing between clear, ring, and busy signals.

The kit comprises two robust, battery-powered units. The compact transmitter operates at a 1.5kHz tone frequency and is powered by a standard 9V PP3 battery. The receiver features a broad frequency detection range from 100Hz to 300kHz, also powered by a 9V PP3 battery, ensuring sensitive and reliable signal detection across various applications. Ergonomically designed, both tools are built for comfort and durability during prolonged use on-site.

Key Applications

• Identify and trace individual wires or cables within a group.
• Check the continuity of cables and wires.
• Locate break points and faults in wiring.
• Diagnose the states of telephony lines (clear, ring, busy).

This professional-grade tester eliminates guesswork, saves valuable time, and prevents unnecessary damage to installations, making it a must-have for any toolkit involved in installation, maintenance, or troubleshooting of electrical and communication systems.
