Fixed point of thermometer
Web• In the Kelvin Scale, the fixed points are 273 K (melting ice) and 373 K (boiling water). • To convert from Celsius (ºC) scale to Kelvin scale: Kelvin temperature = Celsius temperature + 273°C or T (K) = T (ºC) + 273°C f Thermocouple • A thermocouple consists of a mechanical junction of two dissimilar metals. WebFixed infrared pyrometer measures temperatures from 482 to 5432°F even in low visibility, 0.8 to 1.75µm spectral range, up to 1ms response time . Fixed, compact infrared pyrometer measures the temperature of metals from -58 to 1886°F, 8 to 14 µm spectral range.

WebMay 4, 2024 · Thermometry Measurement Services The Standard Platinum Resistance Thermometer Laboratory (SPRTCL) calibrates long-stem and capsule Standard Platinum Resistance Thermometers (SPRTs) at ITS-90 fixed-points from the Argon Triple Point (84 K) through the Silver Freeze Point (1235 K). The precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high temperature work it may only be possible to measure to the nearest 10 °C or more. Clinical thermometers and many electronic thermometers are usually readable to 0.1 °C. Special instruments can give readings to one thousandth of a degree. However, this p…
