The most recent official temperature scale is the International Temperature Scale of 1990. Internationally agreed temperature scales are designed to approximate this closely, based on fixed points and interpolating thermometers. The modern thermometer gradually evolved from the thermoscope with the addition of a scale in the early 17th century and standardisation through the 17th and 18th centuries.345Contents1 Temperature1.1 Early developments1.2 Era of precision thermometry2 Registering3 Physical principles of thermometr圓.1 Thermometric materials3.2 Constant volume thermometr圓.3 Radiometric thermometry4 Primary and secondary thermometers5 Calibration6 Precision, accuracy, and reproducibility7 Indirect methods of temperature measurement8 Applications8.1 Nanothermometry8.2 Cryometer8.3 Medical8.4 Food and food safety8.5 Environmental9 See also10 References11 Further reading12 External linksTemperatureeditMain articles: Temperature and Temperature measurement An infrared thermometer is a kind of pyrometer (bolometer).While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Thermometers are widely used in technology and industry to monitor processes, in meteorology, in medicine, and in scientific research.Some of the principles of the thermometer were known to Greek philosophers of two thousand years ago.

Instrument temperature measurement accuracy to 1.0 of reading is achieved by employing an automatic internal cold end junction compensator to prevent temperature measurement errors due to ambient temperature variations. This digital thermometer pyrometer is ideal for temperature measurement using thermocouple thermometer K type thermocouples.
