Description: | A barograph is an instrument which measures and records atmospheric pressure. The cylinder slowly rotates and, as the pressure moves the pen up and down, a line is drawn onto the scaled paper. This barograph was made by the well-known Newcastle instrument maker F. Robson and Company in the late 1800s or early 1900s. It belonged to Charles Parsons and was used at his Heaton Works.
