Raytech Digital Micro ohm meter, Micro Junior 2, was designed for high degree of accuracy to measure very low resistances. It is battery operated with a lithium-ion battery that allows over 2000 test measurements with 10A output without recharging.
The MJ-2 is a high precision, fully automatic, microprocessor based system. This system is designed for highly accurate readings on-site with laboratory precision.
The MJ-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 Micro Junior 2 is one of the most lightweight systems available that comes complete with its own rugged waterproof Fieldcase.
