MD 15KVR
The digital insulation tester model MD-15KVR is Megabras' cutting edge insulation analyzer equipment and it is one of the most complete and sophisticated available in the international market. A powerful software allows for further analysis of tests results, including features such as graphical representation and automatic report generation. Its proven technology provides safe, reliable and accurate measurements of insulation resistances up to 15 TΩ, with 4 pre-selected test voltages, 500 V - 5 kV - 10 kV - 15 kV. Other test voltages may be selected in steps of 25 V, 100 V or 500 V.
A state-of-the-art microprocessor controls the equipment operation and enables the incorporation of advanced features which make measurements easier: auto-range selection, 16,000 readings memory, AC/DC voltmeter, automatic measurement of Absorption Index and Polarization Index, leakage current and capacitance measurement, timer enabling programming of test duration, configurable Pass-Fail test, Step voltage test, real time clock and calendar. Built-in chronometer, indicating elapsed time, in minutes and seconds, since the test started, up to 90 minutes.
Measured values are transmitted through the USB interface and are printed in the built-in printer as a registration of the performed test.The MD-15KVR has a Bluetooth interface that allows remote control of it through a Android device with BlueLogg software. With it you can take the photos of the objects under test and the GPS coordinates of each. It also allows you to record voice comments for each measurement.
