MI 3252 Micro-Ohmmeter 100A

Metrel MI 3252 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 MI 3252 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%)
