Cropico DO5000 Series Micro Ohmmeters

The Cropico DO5000 Series offers a range of high-performance micro ohmmeters designed for laboratory testing, production line quality control, and automated test systems. Combining precision, advanced features, and portability, the series provides the ideal solution for low resistance measurement across a wide range of applications.

All models in the DO5000 Series feature true 4-terminal measurement to eliminate lead resistance errors, automatic temperature compensation, Hi/Lo limit sorting, and built-in data logging. Statistical analysis, cable length calculation, and programmable measuring current functions make the series exceptionally versatile.

With models available for general testing, portable field use, and advanced automated integration, the DO5000 Series can be tailored to your requirements.
