The 742A are high accuracy working standards for precision, on-site resistance calibration. Excellent temperature stability means they are able to be used from 18°C to 28°C with typically less that 2ppm degradation. Easy to transport and care has been taken to reduce resistance changes brought about by thermal and mechanical shock.
