Product Overview: AEMC 6255 10A Micro-Ohmmeter

The AEMC 6255 10A Micro-Ohmmeter Model 6255 is a rugged, low resistance tester designed for both plant maintenance and field use. Utilizing a four-lead Kelvin method, the Model 6255 is the most accurate Micro-Ohmmeter available, with results within 0.05%.

AEMC 6255 is uniquely designed to conduct tests on both resistive and inductive material, with operator selection directly from the front panel. Three test modes are available; resistive (instantaneous test), inductive (continuous test), and auto (repetitive test). Up to 1500 measurements can be stored and printed directly to a printer from a PC.

The DataView^® Software included allows you to configure the instrument, store data and print reports.
