pyrometricaladj.

Brit.

/ˌpʌɪrə(ʊ)ˈmɛtrᵻkl/, U.S.

/ˌpaɪroʊˈmɛtrək(ə)l/

Origin: Formed within English, by compounding. Etymons: pyro- comb. form, -metrical comb. form.

Etymology: < pyro- comb. form + -metrical comb. form, after pyrometer n. With sense 2. Compare earlier pyrometric adj.

Physics and Engineering.

†1. = pyrometric adj. 2. Cf. pyrometer n. 1. Obsolete.

1803 Philos. Trans. (Royal Soc.) 93 127 And, (similar to what has been observed in pyrometrical experiments,)..these pieces of metal did not, upon the cessation of friction, return precisely to their original size.

1912 Proc. Royal Soc. A. 87 452 The main object being to fix for pyrometrical purposes the true temperature corresponding to the ‘black body’ temperature of molten copper.

1991 Proc. SPIE (Internat. Soc. Optical Engin.) 1598 175 There are some commercial laser soldering systems available, using different types of process control, e.g. pyrometrical temperature measurement.
