What is a Barograph

A barograph is a recording aneroid barometer where the changes in atmospheric pressure are recorded on chart paper. A barograph chart is mounted on to the drum which is normally turned by clockwork. The ink trace, or barogram, on the recording paper is a visual record of changes in pressure. The barogram trend shown can be invaluable in forecasting weather changes.

Metcheck specialise in supplying exquisitely made Barography in numerous sizes and wood finishes. To complement these traditional instruments we stock an extensive back catalogue of barograph consumables such as charts, pens and ink. We often get asked for best practice advice, so if you are new to using a Barograph for pressure measurements, or have inherited a family heirloom, our 'Barograph How to Guides' may be helpful when it comes to setting or calibrating your instrument.
