Mastech MS5203 Professional-Grade Digital Insulation Resistance Tester

Description

The Mastech MS5203 is a professional-grade digital insulation resistance tester, also known as a "megohmmeter". It is designed for precisely evaluating the insulation integrity of high-voltage electrical equipment and systems. The MS5203 is suitable for electricians, technicians, and maintenance professionals who need to perform accurate and reliable high-voltage electrical diagnostics.

Key Features

• High-voltage insulation testing: The MS5203 can perform insulation resistance tests at selectable DC voltages of 50V, 100V, 250V, 500V, and 1000V. The maximum measurable insulation resistance is 10 GΩ.
• Insulation analysis: For advanced diagnostics, it automatically calculates the Dielectric Absorption Ratio (DAR) and Polarization Index (PI) to assess the condition of electrical insulation over time.
• Multifunctional capabilities: In addition to insulation testing, the device also functions as a multimeter, capable of measuring AC voltage up to 750V and DC voltage up to 1000V, as well as checking resistance and continuity.
• Data handling: The unit features a storage function to save up to 20 groups of data for later review. It also has data hold, Min/Max/Avg, and relative measurement functions for comprehensive data analysis.
• Interface and display: It comes with a large, backlit LCD that includes both a digital and analog bar graph display, making it easy to read measurements in various lighting conditions.
• Safety features: Rated for use in CAT III 1000V and CAT IV 600V environments, the MS5203 includes double insulation for user safety. It is also equipped with auto power-off and low-battery indicators.
• Durability: The robust design is non-slip and anti-fall, with an integrated stand and soft rubber holster for protection.
