вимірювання температури

The methodological bases  for  the study of  the systematic error of  temperature measurement by  liquid-in-tube thermometers  and microthermometers with  diminution  of  the  capillary  diameter,  that  is, when  passing  from  thermometers  to microthermometers, in the  field of predominance of gravitational forces over surface tension  forces, are given.

The major error of temperature measurements of different objects is due to uncertainty of their emissivity factor value. And vice versa, for correct determination of a true temperature, using conventional temperature means (pyrometers, thermal image cameras), one has to know in advance the emissivity factor of the studied object’s surface or better to set its value in place immediately  before  a  measurement.  The  latter  is  proposed  by  authors  to  significantly  increase  the  accuracy  of  temperature measurement.
