Improving Dry-Well Calibrations
Applications tip from Hart Scientific- Extract:In practice, many customers use a dry-well as both a heat source and a reference thermometer. In other words, they put their thermometer or sensor to be tested in the well and compare its reading to the tempe
DRY-WELL THERMOMETER CALIBRATORS (pdf)
Abstract – Typical specifications for dry-well thermometer calibrators may not provide all the uncertainty information the users need to know. This paper defines other important criteria for making accurate thermometer calibrations using dry-well or “dry-
