IRM-5000P
Insulation Resistance Meter
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.
