Martindale ET4 Electrical Tester 200A AC/DC


A compact electrical tester that measures AC/DC voltage, resistance and AC/DC current. It will also measure frequency, continuity and will take simultaneous measurement of current/voltage and frequency/voltage. This electrical tester can be used as a non-contact voltage indicator and has auto ranging, display hold and auto power off functions.

One of the forks has a forward facing LED light to illuminate the area in the front.

The ET4 is supplied with TL17 test leads, a soft carry case, 9V battery and manual.
