Megger tester 2.5kv is a high-voltage insulation resistance tester that uses a DC charge to measure the resistance of electrical insulation, helping to identify faults, prevent short circuits, and ensure electrical safety. It typically offers direct test voltages up to 2,500 volts (2.5kV), adjustable test voltages, a large display for accurate readings, built-in memory for storing results, and functions like Polarization Index (PI) and
