brontometer
Definitions
An instrument for noting or recording the phenomena that accompany a thunderstorm.
Examples
“The fans make⟳ one revolution for each metre of wind that passes, and send⟳ an electric current to the brontometer, where it acts on an electro-magnet, and tends to draw⟳ this (2nd) pen towards the left; but a train⟳ of clockwork is constantly tending to draw⟳ the pen to the right, the joint result⟳ being that the pen continuously shows, not the total motion (as is the case with most anemometers), but the actual velocity almost second by second.”
