The Martindale TEK404 is a simple to use, continuity tester with audible and visual indication. This compact tester provides audible indication with a loud 85 dB buzzer and visual indication by a bright LED.
It can be used for the same low voltage applications as the TEK402 with the added benefit that it’s also suitable for use in CAT II and CAT III environments. There is an additional safety feature which pulses to alert the user when connected to live circuits >30V AC.
There is a convenient belt clip and the TEK404 is supplied with CATIII 600V rated TL47 test leads.
