## Description

The Triplett ET30 Magnetic Field Detector quickly determines the presence of magnetic fields (AC/DC/Permanent). It can test solenoid valves in pneumatic/hydraulic control equipment, relays with coils, electrically controlled solenoid valves in vehicles/machinery/oil burners, and audio speaker coils. It features a built-in self test magnet, LED flashlight, and a low battery indicator. Includes (2) AAA batteries.

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.
Review: Don't waste your money - Poor quality all around. Package a pain to open, battery compartment opening very difficult to figure out and, oh yeah, it does NOT detect any magnetic fields. Poor value, does not function, difficult to use. Flashlight works ok, but doesn't stay on unless you keep your finger on the button.
