Precision Milliohmmeter & Insulation Resistance Test Kit with Multimeter Functions and Data logger
The Metrahit IM Xtra is a portable high Precision Milliohmmeter with a wide resistance measuring range and test currents of 200mA and 1A offering a basic accuracy of 0.5% and a max resolution of 0.001mΩ suitable for checking low contact resistance/switchgear connections. Combined with an Insulation Resistance Tester for testing at 50V, 100V, 250V, 500V & 1000V plus a Precision Multimeter with the highest measurement safety category of 1000V CAT III/600V CAT IV making it the most suitable instrument for carrying out these tests on systems with voltage levels up to 1000V AC/DC.
What we like:
The Metrahit IM is the only instrument that offers both a 4 Wire Precision Milliohmmeter and Insulation Resistance Test in a single portable unit! The Metrahit IM Xtra covers both low value milliohmmeter measurements and high value mega ohm insulation resistance measurements. It’s also offers a control probe so that you can start measurements while holding the probes in the contact position and then store test readings on the go which is great when you need to make lots of insulation resistance measurements at different ground test points and 2-wire low resistance measurement at 0…3/0…30 Ω with 200 mA test current which meets the requirements of EN 61557-4 for resistance of earth connection and equipotential bonding on low voltage distribution systems.
