Series of Primary High Value 2 Terminal Resistors from 10 MΩ to 100 TΩ with Optional Carrying Case
The 9331G series of high accuracy resistance standards are available in standard values from 10 MΩ to 100 TΩ and custom values available at any resistance therein.
High stability and supplied alpha and beta temperature coefficients of the 9331G make them ideal for easy transport and operation in any working environment within the range of 18 to 28 °C. The resistance standards require no controlled oil or air bath to meet specifications, however, for improved performance, they can be placed in an air bath such as the Model 9300 or 9300A.
The Model 9331G is based on a NIST design which includes the split guard design and internal temperature sensor. The split guard circuit design allows for applying independent guard voltages at each side of the resistor.
All resistor connections are type N. Several adapter cables from N Type to GR, BNC etc. are available.
The Model 9331G is hermetically sealed in a shielded enclosure and isolated from the case.
