        Major Tech MT987 | Micro-Ohmmeter DC resistance Tester | 20A

        The Major Tech MT987 is a high-precision 20A Micro-Ohmmeter designed for professional electricians. It is also known as a transformer DC resistance tester, DC resistance quick tester, and earth continuity tester. This device uses advanced microprocessor technology to ensure safe, accurate, and reliable testing.

        The MT987 measures the resistance of transformer windings, earth conductor continuity, and wire resistance of cables, switches, connectors, relays, coils, motors, equipment casings, and more. It is equipped with a 108mm x 65mm true-colour touch screen and offers a maximum resolution of 0.1µΩ.

        The tester includes features like a built-in printer, data storage for 800 sets, USB and Bluetooth connectivity(Bluetooth allows connection to Android phones), and a reminder for discharge probes on the LCD. The MT987 is powered by a 14.6V 12000mAh rechargeable lithium battery and is ideal for use in various industrial applications.
