Megger IMT100 Industrial Multi-Tester

Powerful, intuitive, and rugged, the Megger IMT100 is a professional-grade multi-function tester crafted for demanding sectors—including photovoltaic (PV) installations, electric vehicles (EV), rotating machinery, and industrial systems. This all-in-one instrument blends safety, precision, and versatility to tackle a wide spectrum of diagnostic and commissioning tasks.

Core Features

• All‑in‑One Testing Tool – Combines insulation resistance, low-resistance bonding (Kelvin 4-wire DLRO), continuity, voltage (AC/DC), phase rotation, frequency, capacitance, inductance, temperature measurement, and motor direction testing. 

• Standards-Compliant & Future-Ready – Meets IEC 62446 for PV systems and UN ECE R100 for EV applications, with adherence to safety standards IEC 61010, IEC 61557, and EMC IEC 61326. 

• Safe & Rugged – Equipped with fast-detecting circuitry, live circuit detection, insulation test lockout (25V–75V), and CAT III 600 V safety rating. Its over-molded, IP54-rated housing withstands moisture and dust, perfect for outdoor or rooftop settings. 

• High-Precision Insulation Testing – Measures up to 200 GΩ, offers spot, timed, PI (Polarization Index), and DAR (Dielectric Absorption Ratio) tests, with variable, stabilized test voltages up to 1 kV and a guard terminal for accurate leakage measurement. 

• Accurate Low-Resistance Testing – DLRO mode ranges from 1 mΩ to 10 Ω with a 200 mA test current. Supports auto/manual, uni-/bi-directional testing, plus lead resistance compensation. 

• Advanced LCR & Temperature Functionality – Automatically identifies inductive, capacitive, or resistive elements up to 1 kHz, with selectable inductance/capacitance measurement and temperature compensation via included thermocouple (CAT III 600 V). 

• Intuitive Interface & Smart Storage – Features a full-color graphic display, rotary dial, and soft keys. Stores up to 256 test records with tag & date, easily downloadable via USB or accessible through onboard dashboard.
