MI 9210B reference series precision standard resistors

MI 9210B reference series precision standard resistors

Through years of technological experience in developing the most accurate and stable resistance standards available, Measurements International has developed the model MI 9210B reference series of precision standard resistors. The 9210B uses oil-filled resistors in a closed housing. This design provides immunity to changes in barometric pressure and humidity.

These resistance standards are designed to be used in the MI 9400 temperature controlled oil or 9300A air bath to achieve their specifications. However, for optimum performance as a primary set of resistors, it is recommended to place the resistors in the Measurements International model 9400 Oil Bath. Connections to the 9210B are made at the top of the resistor. The resistors are compact in design and can easily meet the need to be 4 inches below the top of the oil.

Connections to the 9210B are made using Tellurium copper binding posts.

A connecting cable can also be ordered with the 9210B resistor stands. The connecting wire is supplied in two or four wire configurations. The wire can be ordered in lengths with already mounted screens or in rolls of 100 meters. No. 18 gauge solid copper, silver plated, shielded Teflon cable is recommended.

Each 9210B is supplied with a calibration report including the assigned value and temperature coefficient data. The small robust design allows for commercial transportation.
