Features & Benefits

Through Years of technological experience developing the most accurate and stable resistance standards available, Measurements International has developed the Model 9331R Reference Series of Precision Standard Air Resistors.

This 9331R series air resistor was developed to close the gap between high accuracy and high stability oil resistors with the air resistor market. By releasing the 9331R series of air resistors, customers now have an alternative to using oil resistors and still achieve superior measurement results.

The 9331R employs multiple oil-filled resistive elements housed in a sealed enclosure.

The resistance standards require no temperature controlled oil or air baths to achieve their specifications. However, for optimal performance as a primary set Reference Series Standard Air Resistors MODEL 9331R of resistors, it is recommended that the resistors be placed in the Measurements International’s Model 9300A Air bath.

Connections to the 9331R are made using Gold Plated Tellurium Copper binding posts. A separate ground is included for grounding the case.

Interconnecting cable may also be ordered with the 9331R Resistance Standards. The interconnecting wire comes in either two or four conductor configurations. The wire may be ordered in lengths with screens already attached or in 100-meter rolls. No. 18 gauge solid copper, silver-plated, screened Teflon cable is recommended.

Each 9331R comes with a calibration report including the assigned value and temperature coefficient data. Each resistor comes with its own carrying case.
