Megger IMT100 Industrial Multi-Tester Product Description
Megger IMT100 Industrial Multi-Tester combines a wide range of electrical test functions in one hand-held instrument for photovoltaic, electric vehicle and general industrial work. It supports insulation resistance, continuity, low resistance bonding, AC and DC voltage, frequency, capacitance, inductance, temperature and motor rotation testing. A full-colour graphic display and rotary control help users select functions and read results clearly during installation, commissioning, maintenance and fault finding.
For insulation work, the instrument provides test voltages of 50 V, 100 V, 250 V, 500 V and 1000 V, together with a variable test voltage from 10 V to 999 V. It also supports Polarisation Index, Dielectric Absorption Ratio, timed testing and temperature compensation. Four-wire Kelvin low resistance measurement, three-phase rotation testing and a guard terminal extend its use across bonding, rotating machinery, PV installations and other electrical systems.
Megger IMT100 Industrial Multi-Tester can store up to 256 date and time stamped results and transfer data through its USB Type A mass-storage interface. Its IP54-rated, over-moulded housing is designed for demanding working environments, while rechargeable batteries support portable operation. Compliance includes IEC 62446 for PV testing, UNECE R100 for electric vehicle testing, IEC 61010-1 CAT III 600 V safety requirements and industrial EMC to IEC 61326.
Key Benefits
- Combines more than 13 testing functions in one hand-held instrument for varied site work.
- Supports PV testing, electric vehicle work and general industrial electrical maintenance.
- Four-wire Kelvin testing improves access to low resistance bonding measurements down to the milliohm range.
- Automatic and selectable test functions help speed insulation, continuity, LCR and resistance testing.
- Full-colour graphic display with configurable backlight makes test information easier to read.
- Stores up to 256 date and time stamped results for organised test record management.
- USB data transfer allows stored results to be moved to a computer or USB mass-storage device.
- Live circuit detection and test inhibit functions help protect the instrument during supported measurements.
- Guard terminal connection can reduce the effect of parallel surface leakage during insulation testing.
- IP54 protection and an over-moulded housing support use in demanding industrial environments.
Common Applications
Megger IMT100 Industrial Multi-Tester is suitable for a range of testing, maintenance and inspection tasks, including:
- Installation, commissioning, start-up and planned maintenance testing.
- Photovoltaic insulation resistance, dielectric absorption ratio and polarisation index testing.
- PV electrical bonding verification and AC or DC voltage checks.
- Electric vehicle AC and DC voltage, insulation resistance, continuity and bonding tests.
- Domestic, industrial and utility electrical installation testing.
- Power generation infrastructure maintenance.
- Rotating machinery, motor and generator testing, including direction of rotation.
- Low resistance bonding measurements using two, three and four-terminal methods.
- Capacitance, inductance, frequency and temperature measurement.
Why Choose This Model?
The IMT100 brings insulation, continuity, four-wire Kelvin low resistance, voltage, LCR, temperature and motor rotation functions into one portable instrument. Its 256-result memory, USB transfer, full-colour display and IP54 housing make it well suited to technicians who need broad test capability in one unit.
