Mastech MS5203 High Precision 1000V Digital Insulation Resistance Tester

Mastech MS5203 1000V High Precision Digital Insulation Resistance Tester

Overview

This high-precision digital insulation resistance tester is designed for checking the insulation of high-voltage electrical equipment such as electric motors, transformers, cables, and more.

Features:

• Checking the insulation of high-voltage electrical equipment (electric motor, transformer, cable, etc.)
• Use 50V-1000V voltage to test target insulation
