## Description

Non-Contact Detector quickly determines the presence of magnetic fields (AC/DC/Permanent) Test solenoid valves in pneumatic/hydraulic control equipment and audio speaker coils Built-in self test magnet and LED flashlight Low battery indicator Includes (2) AAA batteries

Review: Better than expected - Works better than I expected it to for checking DC hydraulic solenoid valves. It is a little tight getting the cap off to swap batteries, but nothing you can't handle with a little flathead screwdriver. The light on this is useless though, but that's not what you're buying this for.
Review: Magnet detector not voltage detector - Excellent magnet detector it helps me to trouble shoot solenoids, for people who doesn’t know this is not a voltage detector.
