Features & Benefits

The Model 4310HR, a six-element resistance standard is the latest development from Measurements Internationals’ series of DC resistors and shunts. After many years of research in resistance materials, the Model 4310HR insures that you get the best performance on the market today. Combined with MI’s experience in automated resistance measurements the 4310HR is used as a temperature controlled, 6-element working resistance reference.

The six-resistance elements cover the range from 100 MΩ to 10 TΩ. The resistance elements feature excellent stability and extremely low temperature coefficients housed in a single unit. Each resistance element is accessible from the back panel with all connections being made via N-type Connectors. The resistor elements are maintained at 30 degrees Celsius, with an operating environment temperature range extending from 18 to 28 degrees Celsius. The Model 4310HR can be mounted in any standard 19-inch instrument rack.

The 4310HR is housed in a double shielded enclosure, with the each inner enclosure being isolated from the external enclosure. This allows the inner enclosure to be driven with active guard voltages.
