Martindale TEK404 Continuity Tester with High Intensity Buzzer and 600 V CAT III LED Indication, Yellow

• Loud buzzer for noisy environments
• Bright LED for visual indication
• Loud 85dB buzzer
• Low cost continuity tester
• Live voltage warning and CAT III 600V safety compliance

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 greater than 30 V AC. The loud 85 dB buzzer makes it ideal for use in noisy environments where many continuity buzzers, multi-meters 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.
