Brand new MIT1025 offers a new compact, light weight 10kV insulation resistance tester for diasnostic and maintenance of high voltage testingn and maintenance of electrical equipment.
CAT IV insultation resistance tester MIT1025 allows the operator to measure insulation resistance up to 20TΩ with all test modes including a ramp test plus advanced memory functions with recall to screen, RTC for time/date stamp of results and USB cable interface to PC / PowerDB.
The MIT 1025 belongs to a new range of smaller and lighter insulation resistance meters than previous models, but it offers advanced features, longer battery life, and fast charging capabilities. It has the ability to operate powered through the electrical network when the battery is depleted. An intelligent battery charger ensures an optimal charging range based on the battery level, resulting in longer battery life and minimal charging times.
The rugged case provides maximum protection for a portable instrument, and the cable bag with clip ensures that the provided cables remain with the instrument at all times. The case cover is removable for better cable access.
The IP rating with the case closed is IP65, ensuring no moisture enters. Highly reliable, all models are rated as CATIV 600 V. In insulation test mode, five preset voltage ranges are provided, as well as a voltage blocking range that the user can configure, which is useful for repetitive measurements at specific test voltages. All test voltages can be adjusted before and during the test with the up/down buttons. Preconfigured diagnostic tests such as the Polarization Index (PI), Dielectric Absorption Ratio (DAR), Step Voltage (SV), and Ramp Test are available along with basic and timed insulation resistance tests. Operation simplicity is achieved with two rotary switches through which the test voltage range and test mode become evident. The large backlit display allows multiple results to be displayed simultaneously, for example, the step voltage test simultaneously displays five step voltage resistance results.
Advanced memory storage includes a date/time indicator of results, data logging, and result retrieval on the screen. A fully isolated USB device interface is used for secure transfer of test records to all versions of Megger's data management software, PowerDB, or popular third-party spreadsheet packages.
