METREL MI 3201 For Parts Insulation Tester

Product Overview

The Metrel MI 3201 TeraOhm 5kV is a high-voltage, professional-grade Insulation Resistance Tester designed for heavy-duty industrial and utility applications. This high-end diagnostic tool is capable of measuring insulation resistance up to 10 TΩ with a programmable test voltage up to 5000V DC. This specific unit is offered For Parts, making it an invaluable resource for repair laboratories or maintenance teams looking for high-precision internal components such as the high-voltage transformer, the specialized LCD assembly, the rotary selector switch, or the robust outer casing.

Key Features (General Specifications)

• High-Voltage Testing: Capable of generating stabilized test voltages from 250V to 5000V in 25V steps.
• Diagnostic Functions: Includes automated calculations for Polarization Index (PI), Dielectric Absorption Ratio (DAR), and Dielectric Discharge (DD).
• Step Voltage Test: Designed to identify insulation breakdown by gradually increasing voltage to detect localized weaknesses.
• Internal Memory: Features an integrated data logging system to store up to 1000 test results for later PC analysis via RS232 or USB.
• Rugged Portable Design: Housed in a heavy-duty "Explorer" style carrying case to protect sensitive electronics from field impact and moisture.
• Large Graphical LCD: Provides clear digital and analog (bar graph) readings of insulation, voltage, and leakage current simultaneously.

Item Condition (For Parts)

• Functional Status: For Parts / Not Working. The unit is sold in its current state for salvage, repair projects, or as a donor for high-value internal parts. It may have a failure in the high-voltage generation circuit, a non-responsive display, or damaged battery terminals.
• Physical State: Shows signs of industrial use. The outer protective case may have scuffs or scratches. The internal fascia and buttons are generally present but may show wear.
• Technical Integrity: No formal calibration or high-voltage output tests have been performed. All components are included "as-is," and their individual functional status is not guaranteed.
• Note: This item is non-returnable. It is intended for skilled technicians who require genuine Metrel parts to restore other MI 3201 units to service.
