  • Description

    Martindale ET4 Multifunctional Electrical Tester

    Detecting voltage from 70 to 600V with its built-in non-contact detector, the Martindale ET4 Multifunctional Electrical Tester is a compact instrument capable of a range of measurements.

    Offering measurement of AC/DC voltage, AC/DC current, frequency and resistance, as well as continuity and diode testing, the Martindale ET4 displays test results shown on its clear LCD screen and boasts simultaneous measurement of current/voltage and frequency/voltage to save time.

    Providing auto ranging functionality, an LED light to aid use in low-lit conditions, display hold and auto power off features, the Martindale ET4 is an ideal instrument for most practicing electricians and comes packaged with TL17 test leads, a soft carry case, 9V battery and manual.
