742A Resistance Standards
- Small and rugged resistance calibrators/li>
- No oil or air baths required
- 18to 28C operating range
- Six-month stability to 2.5 ppm
- Supplied with temperature characterization
742A Resistance Standards are high accuracy working standards for precision, on-site resistance calibration. Their excellent temperature stability allows them to be used from 18 to 28 with typically less than 2 ppm degradation. Using the calibration table supplied with the standards, which lists corrections in 0.5 increments, this uncertainty can be reduced to near zero. No cumbersome oil or air baths are required.
