Major Tech Dead Motor and Phase Rotation Meter MT935

Description

Fast, Accurate Phase Rotation & Motor Testing

Get clear, instant confirmation on phase sequence and motor direction before you energise. The MT935 motor and phase rotation meter uses bright LED indication to show all three phases and instantly identify clockwise or anti-clockwise rotation. This helps prevent costly equipment damage—especially on pumps and motors where incorrect rotation can lead to immediate failure.

Designed for both powered and unpowered systems, you can safely verify motor connections (U, V, W) without mains voltage. That means quicker commissioning, fewer call-backs, and confidence that everything is wired correctly the first time.

Built for Site Safety, Compliance & Durability

Engineered for real jobsite conditions, the MT935 features CAT IV 300V and CAT III 600V safety ratings, giving you peace of mind when working across residential, commercial, and light industrial environments. The double injection rubber housing adds durability and grip, protecting the unit from drops and rough handling on-site.

With non-contact detection capability and clear LED indicators, you reduce risk while maintaining accuracy. The wide operating range from 1VAC to 400VAC ensures flexibility across a variety of installations, making it a dependable addition to any tool kit.

Trade-Ready Design for Everyday Efficiency

Compact, lightweight, and easy to carry, the MT935 is built for electricians who need tools that keep up with demanding schedules. Large crocodile clips make connections quick and secure, even in tight switchboards or motor terminals.

Battery operation (9V included) means you’re ready to go straight out of the box—no downtime, no setup delays. Whether you’re troubleshooting, installing, or commissioning, this tester helps streamline your workflow and reduce time spent diagnosing phase issues.
