The AEMC 2118.78 Spring-Loaded Kelvin Test Probes are designed for use with the 6240, 6250, and 6255 Micro-Ohmmeters (not included). These probes can measure low resistance and can be used with any equivalent micro-ohmmeter with four to six millimeter diameter binding posts or four millimeter diameter safety terminals.

The AEMC 2118.78 Spring-Loaded Kelvin Test Probes improve the contact at the measurement point by removing a thin layer of rust, paint, or dirt. When the user presses on the probe, the probe rotates as it retracts.

Each probe has very low resistance. The measurements are obtained in four-wire mode which eliminates the need for lead resistance compensation. These probes are straight in design which allows for more rugged use.
