Description

Overview

The Marmonix MIR-505 is a high-voltage digital insulation tester with four test voltages (500 V, 1000 V, 2500 V and 5000 V) and measurement up to 60 gigaohm. Built to CAT IV 600 V and featuring a 6000-count display, it suits demanding insulation testing on cables, motors, transformers and switchgear. A built-in voltage monitor to 6000 VDC confirms safe discharge, while high 1-1.2 mA rated current delivers stable readings, making it a reliable tool for high-voltage electrical maintenance and commissioning.
