Major Tech Magnetic Solenoid Tester MT123

Description

Fast, Non-Contact Solenoid & Magnetic Field Testing

The Major Tech MT123 is built for electricians and service technicians who need quick, reliable fault-finding on solenoid valves, relays, and electrically controlled components. Whether you’re working on pneumatic systems, hydraulic controls, vehicles, or industrial machinery, this tester instantly detects active coils without requiring metallic contact.

Designed for real-world trade conditions, it responds to both AC and DC magnetic fields, helping you confirm coil activation in seconds and reduce unnecessary teardown time. Ideal for servicing oil burners, control systems, and field equipment where fast diagnosis keeps jobs moving.

Reliable Detection with Clear Visual and Audible Feedback

When time and accuracy matter, the MT123 delivers immediate results. The red LED indicator and audible beeper provide clear confirmation of magnetic field presence, even in low-light or noisy environments.

Its non-contact detection method improves safety while testing live equipment, allowing you to verify solenoid operation without interrupting circuits or risking damage. With sensitivity across multiple magnetic field ranges, it helps reduce guesswork and supports more confident fault diagnosis on site.

Built for consistent performance, it detects magnetic fields from activated coils and permanent magnets, making it a dependable tool for routine maintenance and troubleshooting across electrical and mechanical systems.

Compact, Jobsite-Ready Design for Everyday Trade Use

The MT123 is designed for electricians who need practical tools that fit easily into their kit. Lightweight and pocket-sized, it’s ideal for daily carry and quick checks across multiple job sites.

A built-in LED flashlight improves visibility in dark switchboards and machinery enclosures, while the simple interface makes it easy to operate without setup delays. Powered by standard AAA batteries, it’s ready for use straight out of the box.

This is a straightforward diagnostic tool that saves time on repetitive checks and helps streamline maintenance workflows for busy contractors.
