1704 J. Harris Lexicon Technicum I Chronoscope, the same with a Pendulum to measure Time.

1731–1800 in N. Bailey Universal Etymol. Eng. Dict.

b. (a) An instrument for measuring very short intervals of time, which has been chiefly used in determining the velocity of projectiles. It was invented by Wheatstone in 1840, and consists of wire targets placed in the line of fire. The projectile passing through these severs the wire, and the moment of severance is recorded by electricity. (b) A device used for measuring the time of reaction in psychological experiments.
