Barographs

Barographs

A barograph is a recording aneroid barometer where the changes in atmospheric pressure are recorded on a paper chart. The recording chart is mounted on a drum which is turned by clockwork. We can supply hand-made instruments for domestic use as well as instruments designed and constructed for a range of industrial purposes.

The Norfolk and The Blakeney barographs both have mechanical eight-day clocks with a seven-day chart which covers one full rotation of the drum. The ink trace, or barogram, on the recording paper is a visual record of changes in pressure and the trend shown can be an invaluable help in forecasting changes in the weather. 

Each instrument is hand assembled and then tested and calibrated to a standard chart in our own pressure/vacuum chamber.

Replacement charts, stainless steel or fibre nibs and different colour inks are available. Charts are available in inches or millibars, starting on a Sunday or a Monday.
