The PX-MST100 photovoltaic safety tester can quickly complete insulation diagnosis operations related to motors (large capacity transformers, transformers, generators, high-voltage motors, cables, lightning arresters). This series of insulation resistance testers has PI (Polarization Index), DAR (Absorption Ratio) measurement and powerful data processing software to complete the recording and analysis of insulation resistance measurement parameters and use this data to determine the quality of insulation conditions.
