How to choose this product

barograph

A barograph is a recording aneroid barometer, an instrument which measures atmospheric pressure over a fixed period and records its fluctuations on a moving sheet of graduated paper or an LCD screen.

Applications

These devices are useful for tracking weather variations, especially disturbances. This information is particularly important to offshore recreational boaters and commercial vessels.

Technologies

Mechanical, analog barographs use a pen on a moving arm to trace pressure changes over time on a sheet of graduated paper mounted on a drum. The pen moves up and down as a function of pressure as the drum rotates at a fixed rate. This produces an easily-read pressure curve. Digital models display the curve on an LCD screen.

How to choose

Analog barographs consume paper, but offer aesthetic advantages. They are often mounted in an attractive case made of fine wood and brass with glass windows.

Advantages

- Graphs real-time pressure changes

Disadvantages

- Bulkier than a barometer
