Top Ten Reasons You Need a Super-Thermometer
	10 Reasons You Need a Fluke Calibration 1594A or 1595A Super-Thermometer Find out the top 10 reasons to choose the Super-Thermometer for your high accuracy temperature measurements.

Papers/Articles
	Putting the 1595A Super-Thermometer to the Test in a Primary Standards Laboratory (Application Note) Temperature fixed point cells are ITS-90 primary standards that demand low uncertainty measurements for calibration purposes. Traditionally, fixed-point cell measurements have been handled by resistance ratio bridges. Ratio bridges have several advantages, but they can be temperamental, susceptible to electromagnetic interference, difficult to repair, and require specialized equipment to verify their continued performance.
	1594A/1595A Super-Thermometer Uncertainty Analysis (Application Note) Metrologists should be proud of their uncertainties. A lot of effort goes into maintaining and improving them, especially in an accredited laboratory. The Fluke Calibration temperature laboratory in American Fork, Utah is well known its performance, not only for some of the lowest uncertainties in the industry, but also for educating other labs about how they can do the same.
	Achieving 0.25 mK Uncertainty with an Integrated-Circuit Resistance Thermometer Readout (Paper) Learn how the author of this paper set out to design a readout for resistance thermometers that achieves less than 1 ppm uncertainty in resistance ratio while overcoming some of the problems of resistance bridges.
	Automatic Linearity Calibration in a Resistance Thermometry Bridge (Paper) Learn about a new system that automatically calibrates the linearity of a resistance thermometry bridge or readout.
	Recent Advances in Resistance Thermometry Readouts (Paper) This paper discusses some of the recent developments incorporated into the Super-Thermometer, which include much improved precision and accuracy; automatic self-calibration of ratio; more stable built-in reference resistors; accurate, traceable sensing current; automatic zero-power resistance and temperature measurements; additional input terminals for thermometers and resistors; and other enhanced features.
