6250

The 10A Micro-Ohmmeter Model 6250 is a rugged, low resistance tester designed for both plant maintenance and field use. Utilizing a four-lead Kelvin method, the Model 6250 is the most accurate Micro-Ohmmeter available, with results within 0.05%.

Resistance measurements are automatically calculated, taking into account the measurement value, ambient temperature, metal type and metal temperature co-efficient. Metal temperature can be manually entered by the operator or directly measured by the Model 6250 with an optional RTD temperature probe.

The Model 6250 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 of from a PC.
