Metrel MI3252 MicroOhm 100A
The MI 3252 MicroOhm 100A is a portable low resistance ohmmeter used to measure low contact resistances of breakers, switches, and busbars using test currents from 100 mA to 100 A.
Metrel MI3252 MicroOhm 100A Features:

Safe: Sustains external voltages in case of wrong connection (CAT IV, 50 V) and automatically detects continuity in the current circuit.
Measuring Modes: Supports both single and continuous measuring modes.
Portable & Rugged: Lightweight design housed in a rugged carrying case (IP 64) for easy transport between sites.
High Accuracy: Offers 1 nΩ best resolution with 0.25% accuracy.
Custom Limits: Set user-defined limits for instant PASS/FAIL evaluation of test results.
Battery Powered: Enables measurements at 100 A for up to 10 minutes when running on the internal battery.
Memory & Data Transfer: Built-in memory stores up to 1,000 test results, downloadable via RS232 or USB using the included software.
