Southwire Precision Voltage Detector and Tester 41171N Series

Southwire Precision Voltage Detector and Tester


Southwire’s 41171N precision voltage detector & tester packs a variety of useful functions into one versatile and powerful electrical tester. It is designed to fit comfortably in your pocket and conveniently performs three of the most common electrician tasks: detect voltage, measure voltage, and test continuity. The tester provides a simple and easy way to test AC and DC voltage up to 600V. Activate the non-contact voltage (NCV) detector for detecting the presence of AC voltage from 100 to 1000V. The NCV alerts you with both a red flashing LED and an audible sounder. There is a handy work light that you can use anytime for those dimly lit areas. The 41171N is also a great continuity tester with both audible and visual confirmation.
