The 2000 series Low Resistance Standards are designed as primary calibration laboratory standards.
One ohm and 0.1 ohm standards are in hermetically sealed, oil filled cans. Lower resistance models are in perforated cans for oil or air circulation.
The 2000-Series standards may also be used as primary level current shunts.
All standards include ISO17025 accredited calibration, with temperature coefficient data at multiple currents.
The 2000 series may be used in air or in a constant temperature oil bath.
Special or intermediate low resistance values are available by special order.
For secondary low resistance standards, please see our 1000-series resistors. For accurate current measurement, please see information on our precision current shunts.
Notes
- Tolerance is accuracy at time of manufacture, and includes calibration accuracy plus 0-100 % rated current.
- Temperature coefficient is at nominal 23 +/-5 °C.
