GPS-4660C

Digital Micro-ohmmeter

The micro-ohmmeter provides reliable, accurate measurements due to its test current of up to 20A. This accuracy is ensured through the use of the 4-wire method which eliminates the effects of the leads' resistances and the contact resistances.

20A DC Current Resistance Tester

This very low resistance ohmmeter is a portable, microprocessor-controlled instrument used to accurately measure resistances of switches and circuit breaker contacts, transformer and motor windings, wire and cable samples, joints in busbars and more.

The GPS-4660C DC Resistance Tester is a high-performance, reliable instrument designed for precise measurement of DC resistance in electrical circuits and components. With a maximum current capacity of 20A, this tester ensures fast, accurate readings, making it ideal for use in power transformers, motors, cables, and switchgear applications.

Engineered for both industrial and laboratory environments, the 4660C features advanced microprocessor control for stable performance. Its large digital display ensures clear visibility of readings, while user-friendly controls simplify operation. The built-in data storage function allows for convenient record keeping, making it easy to track test results over time.
