IP67 Rated*
The 40150N has a job to do- and it won't be stopped by dust or water. The 40150N features a rugged housing, and is IP67 rated to be water resistant and dustproof so that it can stand up to the most demanding environments.
*Certification No.: US-28850-UL

Low Voltage
Dual sensitivity allows detection of voltage in low voltage circuits down to 12V AC as well as higher voltage up to 1000V AC.

Built-In Worklight
Extremely durable high-powered built-in worklight, now two times brighter than ever before. As well, there is a front facing flashlight for multi-purpose use. Flash and beep rate increase as the detector gets closer to the voltage source helping the user pinpoint live circuits easily and quickly.

Low Battery Self-Test
When the tester is on and the batteries are too low for reliable operation, the beeper will sound three times and the green LED will turn off indicating the tester is not operable. This feature greatly enhances safety when using the 40150N.
