refractometern.

Brit.

/ˌriːfrakˈtɒmᵻtə/,

/rᵻˌfrakˈtɒmᵻtə/, U.S.

/rəˌfrækˈtɑmədər/,

/riˌfrækˈtɑmədər/

Origin: Formed within English, by compounding. Etymons: refract v., -ometer comb. form.

Etymology: < refract v. + -ometer comb. form. Compare French réfractomètre (1875).Quot. 1854 is from a translation of a French paper published in 1853, where the instrument is called réfracteur interférentiel; the term réfractomètre is not used in the original paper.

Physics and Chemistry.
