Metrel MI3252 Portable Low Resistance Ohmmeter

The Metrel MI 3252 comes complete with rugged carry case and weighs in at less than 12 kg.

Regardless of its powerful internal generator, the MI 3252 is battery-powered, making it particularly suited to locations with multiple testing points. The high test current enables great repeatability of results, very high resolution and accuracy necessary for measurements of circuit breakers, switches in high-power installations, bus bars, cable splices, welding joints and other very low resistance, high power devices. Results are additionally visualised with a bar graph. The memory can hold up to 1000 results, enough for even the most complex measuring locations. These can then be transferred to your PC using the included HVLink PRO software.

 

Metrel MI3252 Measurement Functions:

  • Low contact resistances of circuit breakers, switches and busbar joints
  • Resistance measurement with adjustable test current (100 mA … 100 A)
  • Voltage drop measurement
  • Eliminates of test leads resistance - Uses 4-lead Kelvin testing method to ensure high accuracy results (0.25%)

 

 

Metrel MI3252 Key Features:

  • 1 nΩ best resolution with 0.25% accuracy
  • 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 modes
  • Custom limits can be set for PASS or FAIL evaluation of test result
  • High protection degree: IP 64
  • Built-in memory enables storage of up to 1000 test results
  • The instrument can be powered from both mains supply and internal battery
  • HVLink PRO software supplied as a standard accessory enables downloading, analysis and export of test results and printing of test reports
