Vanguard Instrument Company’s Model IRM-5000P Megohmmeter is a micro-processor based, high-voltage, insulation-test meter. The Model IRM-5000P is rugged and portable, making it ideal for use in electric-utility substations and for industrial application.

This sophisticated insulation tester uses a dual-microprocessor design. One microprocessor is dedicated to the control of the power supply and measuring circuitry. The second microprocessor is dedicated to the display, printer control, and user interfaces.

• Dual-processor design
• Perform PI, SV & DD tests automatically
• Test duration from 1 to 90 minutes
• Automatically discharge test voltage
• Measures capacitance of DUT
• Store up to 100 test reports
• IR temperature probe, provide equivalent resistance reading at 40°C/10°C
• Built-in 2.5" thermal printer
• Computer Interface
