Keeping You Safe 
The TEK402 is a compact continuity tester with audible indication. The tough construction makes it ideal for industrial and commercial environments including low voltage signalling, process control and training or educational applications.
The loud 85dB buzzer makes it ideal for use in noisy environments where many continuity buzzers, multimeters or 18th Edition multifunction testers cannot be heard.
