| The Megger® BM25 is a compact,automated 5 kV Insulation Tester,used to carry out Polarization Index |
| The Megger® BM25 is a compact, automated 5 kV Insulation Tester, used to carry out Polarization Index, Step Voltage and Dielectric Discharge diagnostic tests as well as standard Insulation Test up to 5 TOhms.
Results and test options are shown on a large, clear analogue/digital display for both practicality and precision. The BM25 combines the rapid assessment of changing readings with the precision and clarity of a digital readout. The BM25 also provides an optically isolated RS232 port for the direct downloading of test results. |
