Martindale Part No: MARTEK404
The TEK404 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.
The loud 85dB buzzer makes it ideal for use in noisy environments where many continuity buzzers, multimeters or 17th Edition multifunction testers cannot be heard.
There is a convenient belt clip and the TEK404 is supplied with CATIII 600V rated TL47 test leads.
