The Krohn-Hite PCR100 Precision Current Resistor is a highly accurate on-site current resistor (standard) with excellent temperature stability that can be used from 20°C to 26°C. A calibration graph is supplied with each PCR100 that shows all corrections in 0.5°C increments, reducing uncertainty to near zero. No cumbersome oil or air baths are required. Because the PCR100 is small and rugged, it is easy to transport. Care has been taken to reduce resistance changes brought about by thermal and mechanical shock. Retrace (permanent shift in resistance) is typically <2ppm after cycling between 0°C and 50°C.
