Through years of technological experience developing the most accurate and stable resistance standards available, Measurements International has developed the model 9210B Reference Series of Precision Standard Resistors. The 9210B uses oil-filled resistive and coil elements housed in a sealed enclosure. This design offers immunity to changes in barometric pressure and humidity.

For optimal performance as a primary set of resistors, it is recommended that the resistors be placed in Measurements International's model 9400 Oil Bath, although they will achieve their specifications in a 9300A Air Bath.

Connect to the 9210B's tellurium copper binding posts at the top of the resistor. The resistors are compact in design and can easily meet the need of sitting 4 inches below the top of the oil. An interconnecting cable may also be ordered with the 9210B Resistance Standards. The interconnecting wire comes in either 2- or 4-conductor configurations 1. The wire may be ordered in lengths with attached screens or in 100-metre rolls.

Each 9210B comes with a calibration report including the assigned value and temperature coefficient data. The small rugged design allows commercial transport.
