Model SR102 - Primary Resistance Standard (100 Ohm)

DESCRIPTION: The SR102 is a highly stable and accurate (1ppm), 100, 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.

Model SR104 - Primary Resistance Standard (10k Ohm

DESCRIPTION: The SR104 is a highly stable and accurate (1ppm), 10k, resistance standard. SR104 standards are equipped for five-terminal measurements used in Standard Resistor readings and for Temperature Sensor readings. Individual 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.
