The Quantized Hall Resistance Standard is internationally recognized as the representation of the ohm and is the most stable resistance standard known. Many National Laboratories and industries are finding a need to provide highly accurate, traceable reference standards in support of their “hi-tech” environments. The 6800B system has been developed to meet the needs of National Laboratories and Primary Industrial Laboratories around the world. The MI 6800B (Quantized Hall Resistance Standard) is a fully automated primary standard developed as an economic means to provide a highly reproducible resistance standard. This system is a completely “turn-key” system and requires little to no manual intervention. A wide neck storage Dewar and instrumentation rack are mounted on castors for portability. A variable temperature pumped 4He refrigerator with integral 8 Tesla, or optional 9 Telsa magnet can be installed.
