MI 3252 MicroOhm 100A is a portable low resistance ohmmeter used to measure low contact resistances of breakers and switches, busbars using test current from 100 mA to 100 A with resistance measurement: wide measuring range from 1 nΩ to 20 Ω, adjustable test current (100 mA ... 100 A), voltage drop measurement, and on screen resistance bar graph.


  • Safe: sustain external voltages in case of wrong connection, protection level (CAT IV, 50 V); automatically detects continuity in current circuit.
  • Single and continuous measuring mode.
  • Portable: rugged carrying case with a handle and lightweight design enable easy moving the instrument between sites.
  • High protection degree: IP 64.
  • Accurate: 1 nΩ best resolution with 0.25% accuracy.
  • Custom limits: the limits can be set for PASS or FAIL evaluation of test result.
  • Battery powered: the instrument enables measurements with 100 A for up to 10 minutes when powered from internal battery only.
  • Memory: built-in memory enables storage of up to 1000 test results.
  • Downloadable: downloads test results via RS232 or USB cable directly to the PC with the help of the software.
