While the introduction of yet another cryogenic diode thermometer is not earth shattering, a new diode thermometer, the DT-600 series, recently introduced by Lake Shore Cryotronics, possesses three features that make it unique among commercial diode thermometers. First, these diodes have been probed at the chip level, allowing for the availability of a bare chip thermometer matching a standard ...

−47− Synthesiology English edition Vol.1 No.1 (2008) In the 1990s, a U.S. company developed a new infrared clinical thermometer in which measurement was taken by inserting the sensor probe into the ear canal (hereinafter will be called “ear thermometer”), and was marketed in the United States and Europe. Figure 1 shows the external appearance of ear thermometers and the schematic diagram of the...

The hydrostatic pressure correction coefficient of the traditional triple point cell of water is determined from the measurements of temperature distribution along the thermometer well. The hydrostatic pressure coefficient obtained from these measurements is −0.855(30) mK/m, which is slightly different from the recommended value, −0.73 mK/m, of the International Temperature Scale of 1990. The l...

OBJECTIVE To assess the accuracy of the tympanic membrane thermometer for use with pregnant women. DESIGN Cross-sectional descriptive study. SETTING A major medical center in the midwestern United States. PARTICIPANTS Thirty-three hospitalized, afebrile pregnant women. MAIN OUTCOME MEASURES Tympanic membrane thermometers and glass mercury thermometers were used to measure body temperatu...

Clinical glass thermometers This article will cover checking the temperature using a clinical glass thermometer which contains mercury. This is the most accurate and most commonly used thermometer. Digital thermometers are available but they require batteries which may not be readily available. WARNING: Mercury is toxic. If a thermometer breaks, put on gloves and use a tissue or a piece of clot...

We have investigated theoretically the effects of the charging energy to the normal metal–insulator–superconductor (NIS) tunnel junction used as a thermometer. We demonstrate by numerical calculations how the charging effects modify NIS thermometry, and how the voltage–to–temperature response and the responsivity |dV/dT | of a current biased thermometer are affected. In addition, we show that t...
