Martindale BZ701 Audible Socket Tester

The Martindale BZ701 Audible Socket Tester is a reliable solution for testing socket wiring and mains polarity with efficiency and ease. It offers users instant visual and audible feedback on the condition of socket wiring, detecting up to 28 different fault conditions. Its intuitive design includes red and green LED indicators along with a buzzer for clear and immediate notification of wiring issues.

Check Supply Polarity with Ease

This socket tester allows for quick checks of the incoming mains supply polarity using its innovative Blue Polarity Touchpad. If the polarity is correct, the green LEDs flash and a continuous buzzer sounds, giving clear confirmation. In the case of incorrect polarity, the LEDs turn red and the buzzer emits a pulse tone. This alerts the user to investigate further. The Martindale BZ701 keeps the fault indication active even after the touchpad is released. This ensures ongoing feedback, so no fault goes unnoticed.

The BZ701 enters standby mode after ten minutes of inactivity. This helps conserve energy. During standby, it provides subtle feedback with a flashing amber light and an alert tone every 5 seconds. With a CAT III 300V rating, this tester is a safe and robust solution for professionals checking socket wiring and supply polarity in both domestic and commercial environments.

Key Features
  • Tests incoming mains supply polarity with a simple touchpad
  • Detects up to 28 socket fault conditions
  • Visual LED indicators for quick diagnosis of faults
  • Audible buzzer for easy fault identification
  • Enters standby mode after ten minutes of inactivity
  • High and low voltage indication for mains supply
  • Red/green LED indicators for wiring fault alerts
  • Durable design with clear N, E, L labelling for quick identification
  • Offers standby alerts via flashing amber light and periodic tone
  • Compact and lightweight, ideal for professionals on the move
