Experience the pinnacle of precision and stability with the Model 9331R Reference Series of Precision Standard Air Resistors from Measurements International. Drawing on decades of expertise in the field, we have created a groundbreaking solution that bridges the gap between high accuracy and high stability.

The Model 9331R series of air resistors offers a superior alternative to traditional oil resistors, delivering superior measurement results without the need for temperature-controlled oil or air baths. Employing multiple oil-filled resistive and coil elements housed in a sealed enclosure, the Model 9331R is the perfect choice for demanding applications.

For optimal performance, we recommend using the Model 9331R in conjunction with our Model 9300A Air Bath. Connections to the Model 9331R are made with ease thanks to the silver-plated tellurium copper binding posts and separate ground for case grounding. Additionally, an interconnecting cable may be ordered in either two- or four-conductor configurations, with the option of already-attached screens or 100-metre rolls of No. 18 gauge solid copper, silver-plated, screened Teflon cable.

Upgrade your measurement systems with the Model 9331R Reference Series of Precision Standard Air Resistors and experience the benefits of high accuracy and high stability."

Each 9331R comes with a calibration report including the assigned value and temperature coefficient data.
