MPK215e High Current Micro-ohmmeter

The MPK215e is a portable, microprocessor-controlled instrument designed for the accurate measurement of very low contact resistances in breakers, switches, busbars, transformer windings, and engines. With test currents from 5 A to 200 A, the MPK215e provides precise results using the 4-terminal method, eliminating errors caused by test leads and contact resistances.

It offers high accuracy with resolutions down to 0.1 μΩ, digital storage and reporting capabilities, and robust construction for both field and laboratory use. Lightweight yet durable, the MPK215e is water-resistant, impact-resistant, and designed to operate under severe environmental conditions.

Function

• Accurate low resistance measurement for breakers, busbars, transformers, and engines
• Test currents adjustable from 5 A to 200 A true DC
• Four-terminal U/I measurement principle eliminates lead resistance errors
• High resolution up to 0.1 μΩ with ranges up to 1 Ω
• Programmable test duration from 5 to 120 seconds
• Internal thermal protection for safe operation
• Built-in memory with USB data transfer and report generation via T-Logger software
• Rugged IP65-rated housing for laboratory and field use
