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. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | inventors and innovators small business made in the North East | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
