Product Introduction

        ND2672A Digital Insulation Resistance Tester, also known as a Megohmmeter or High-Voltage Insulation Resistance Tester, is used for testing insulation resistance. This instrument features a large LCD screen with gray-white backlight, data storage, data review, protection functions, automatic shutdown, and more. It also has the capability to measure DC voltage, AC voltage, absorption ratio, and polarization index. The device boasts an aesthetically pleasing and high-end design, wide measurement range, high resolution, user-friendly operation, portability, accuracy, reliability, stable performance, and strong anti-interference capability.

       ND2672A Digital Insulation Resistance Tester is designed with shockproof, dustproof, and moisture-resistant construction, making it suitable for harsh working environments. It is an essential and commonly used instrument in telecommunications, power, meteorology, data centers, oil fields, electromechanical installation and maintenance, as well as industrial enterprises that utilize electricity as a power source or energy. It is suitable for measuring the resistance values of various insulating materials and the insulation resistance of transformers, motors, cables, and electrical equipment.

        ND2672A Digital Insulation Resistance Tester is composed of medium- to large-scale integrated circuits. This tester offers high output power and multiple output voltage levels (with 5 voltage grades). The rated insulation test voltage range is 250–5000V, and the insulation resistance measurement range is 0.01MΩ–200GΩ. The DC voltage measurement range is 0–1000V, and the AC voltage measurement range is 0–750V.
