Description
Raytech Digital Micro ohm meter, Micro-Centurion II, was designed for high degree of accuracy to measure very low resistances. This technology was then packed into a portable test system to be used by apparatus manufacturers, rebuild shops, and electrical maintenance crews. This intelligent system has an easy to use operation screen, which allows quick selection of the current level and resistance level to be measured.
The MC-2 is a high precision, fully automatic, microprocessor based system. This system is designed for highly accurate readings on-site with laboratory precision.
This newly designed technique of measurement incorporates a high precision measurement circuit and modular power source. Extensive filtering and high precision standards are used within the test system.
The MC-2 applies a preset current level, selected by the user. The results of the test are displayed within a few seconds automatically. The results are reported on the easy to read liquid crystal display and can be stored or printed out.
The Centurion II is one of the most lightweight systems available that comes complete with its own rugged waterproof Fieldcase.
