Product Description

The Megger Insulation Resistance Tester MIT525 is a compact and lightweight 5 kV insulation resistance tester used for the diagnostic testing and maintenance of high-voltage electrical equipment. Here is an overview of it:
Key Features
Multiple Test Functions
In addition to measuring insulation resistance up to 10 TΩ, it also offers various diagnostic tests, including polarization index (PI), dielectric absorption ratio (DAR), step voltage (SV), dielectric discharge (DD), and ramp testing.
Advanced Memory Function
It has advanced memory storage that can log test results with time and date stamping, and allows for simple recall of results to the screen. It can store 5.5 hours of continuous logging at 5 - second intervals, 33 logged PI tests, and 350 logged IR tests.
Convenient Data Transfer
A fully isolated USB interface is used for the safe transfer of data to the supplied Megger Power DB Lite management software package.
Dual - Case Design
The unique dual - case design provides additional user protection and meets the CAT IV 600 V safety rating in accordance with IEC 61010. The protection class is IP65 when the cover is sealed and IP40 when the cover is open.
Easy - to - Read Display
The large backlit display allows multiple results, such as resistance, voltage, leakage current, capacitance, battery level, and test time, to be displayed simultaneously, making it suitable for use in both bright sunlight and poorly lit environments.
Simple Operation
Two rotary switches ensure simple operation, and there is a quick - start guide on the lid to assist first - time users.
