IET Labs – Primary resistance standard, model SR102, 100 ohm
The IET Labs SR102 model is a highly stable and accurate (1ppm), 100 Ohm, resistance standard. SR102 standards are equipped for five-terminal measurements used for standard resistor readings and for temperature sensor readings.
Calibration data, which identifies the standard deviation, and the temperature characteristics is supplied with each unit.
In addition, each unit is equipped with a thermal well so that the exact temperature of the resistance standard is known. This allows the user to make highly precise, temperature compensated, measurements.
Features
- Long term stability of resistance standard... typically less than 0.2 ppm per year
- Temperature coefficients... less than 0.1 ppm per degree Celsius at 23 degrees C
- Initial accuracy... ± 1 PPM
- Units can be supplied without cases for use in oil baths
- 1 year warranty
Applications
- Primary calibration laboratory
- Standard to be transported directly to NIST or a NIST-traceable
- Calibration facility (TEGAM, Inc.);
- To calibrate transfer standards and resistance bridges for NIST-traceable calibrations
- Can be used outside of controlled laboratories, or environments by monitoring the temperature of the unit.
