Product Description

Low-Resistance Test Contact for Micro-Ohmmeter Measurements

The AEMC 2118.78 is a 10A spring-loaded Kelvin probe set with 20 ft leads. Designed for use with compatible AEMC micro-ohmmeters or equivalent testers, it supports 4-wire low-resistance measurement through paired current and voltage contacts.

Spring-Loaded Kelvin Contact with Rotating Probe Action

- Retractable probe tips press into the measurement point to establish contact.
- Rotating tip action helps remove a thin layer of rust, paint, or dirt during contact.
- Voltage probes are identified by red spots to support correct terminal placement.
- Spade lugs connect to binding posts, and removable lugs support 4 mm safety terminal connections.

Electrical and Mechanical Measurement Scope

- Maximum current: 10 A.
- Maximum voltage: 30 V.
- Lead length: 20 ft / 6.30 m.
- Probe diameter: 0.12 in / 3 mm.
- Center-to-center probe spacing: 0.315 in / 8 mm.

Low-Resistance Electrical Testing Applications

- Low-resistance measurement with AEMC 6240, 6250, and 6255 micro-ohmmeters.
- 4-wire Kelvin resistance testing where lead resistance compensation is not required.
- Electrical contact measurement using compatible binding posts or safety terminals.
