Mastech MS5205 Professional-Grade Digital Insulation Tester

Description

The Mastech MS5205 is a professional-grade digital insulation tester, also known as a megohmmeter or "megger". It is specifically designed for testing the insulation resistance of high-voltage electrical equipment, ensuring the safety and reliability of electrical systems.

Key Features

• Multi-voltage insulation testing: The MS5205 can perform insulation resistance tests at selectable DC test voltages of 250V, 500V, 1000V, and 2500V. It can measure resistance up to 100 GΩ.
• Insulation analysis: For advanced diagnostics, it automatically calculates the Dielectric Absorption Ratio (DAR) and Polarization Index (PI).
• Integrated multimeter: It includes multimeter capabilities for measuring AC voltage up to 750V and DC voltage up to 1000V, as well as continuity tests.
• Data functions: The device can store up to 20 sets of measurement data and features a timer function for tracking changes in insulation resistance over time.
• Safety features: It is built with high safety ratings (CAT III 1000V and CAT IV 600V) and includes a function for automatically discharging capacitive loads after a test for user safety.
• Display and interface: It features a large digital LCD with an analog bar graph and a backlight for clear visibility in poorly lit areas.
