MT239 Bluetooth Insulation Resistance Tester with Multifunction Capabilities

Description

MT329 Bluetooth Handheld Multifunction Tester

The MT329 is a powerful, all-in-one multifunction tester designed for professional electricians who need accuracy, versatility, and wireless connectivity in one compact device.

Featuring Bluetooth connectivity, the MT329 allows you to easily download and manage stored test data directly to your iOS or Android device for convenient record-keeping and reporting.

With three insulation test ranges (250V, 500V, and 1000V) and insulation resistance measurement up to 4000 MΩ, this tester delivers reliable performance across a wide range of electrical systems. It also measures AC/DC voltage up to 500V, supports AC+DC mode, and includes a data hold function for capturing and reviewing readings on the go.

The MT329 performs loop impedance testing with a high test current of up to 18.3A, ensuring fast, accurate results—without tripping RCDs rated above 30mA. It also provides PFC and PEFC readings, phase sequence testing, and comprehensive RCD testing for Type A, Type AC, and Type B devices.

Other advanced features include RCD trip time and trip level testing, auto discharge of test voltage, and auto power-off to extend battery life.
