Barographs are recording barometers. They display the trend (up, steady, or down) and the rate of change. And since changes in pressure generally precede new weather, a barograph can help us "see" what's coming.
For instance, rising pressure most often indicates clearing and cooler; falling pressure usually points to warmer, more cloudy, and possible precipitation. A rapid rise or fall is almost always accompanied by higher winds, and unchanging pressure means continuing conditions and little wind. The crest or trough of a pressure curve most often indicates a change of wind direction.
With these few forecasting tips you can use a barograph as your crystal ball.
The English have long been known for fine cabinetry, and it shows in the workmanship of the Windsor, a grand example of what is called an "exhibition" barograph. It has an extremely smooth low-gloss finish over the solid mahogany cabinet, five beveled glass panes, a drawer with two compartments for storing new and used charts, and solid brass hardware. Inside the lift-off cover is a precision aneroid sensor of 8 chrome-plated cells. All other components are of brass. A quartz battery drive rotates the chart drum once per week, and the traditional pen nib leaves a clearly defined trace for easy reading to the weeks pressure. Choose 7-day charts in inches or millibars. Ink, battery, and complete instructions are also supplied. We know of no barograph of this quality available today. Also, ask us about the matching display SHELF made exclusively for this barograph of the highest quality mahogany.

Superior performance and brilliant finish are hallmarks of the Baltic. The high-gloss mahogany cabinet has a hinged top with five glass windows. Inside, the precision movement is gold-plated for corrosion resistance and mirror finish. The heart of this barograph is a stack of eight polished aneroid capsules, assuring outstanding sensitivity to even the smallest pressure fluctuations. A 7-day quartz drive offers excellent timekeeping, and a felt pen gives trouble-free tracing. Evidence of ingenious construction is everywhere. The small screws which secure the windows are covered by rubber sleeves where they pass through the glass. Also, each side of the cabinet is one piece of mahogany - the entire hinged top has only five pieces. This construction is far stronger because there are fewer joints. The Baltic is built better. Supplied with "AA" battery, cartridge felt-tip pen, and 100 weekly charts in your choice of 28.00-31.00 inches or 960-1060 millibars. 10 1/2"L x 7"H x 6 1/4"D.
This close-up reveals the gold-plated finish, the special nameplate, and the rich gloss mahogany which distinguish the Baltic. BA2003

High performance, rugged corrosion-resistant construction, and handsome
satin-finished mahogany cabinet qualify the Atlantic for use offshore as well as
at home. The linkages in this recorder are tight, eliminating the need for
marine damping when used at sea. Further, the Atlantic is more compact than
other barographs using a weekly chart with as much scale resolution. This level
of detail is served dutifully by a sensitive eight cell aneroid sensor. Supplied
with "AA" battery, cartridge felt-tip pen, and 100 weekly charts in your choice
of 28.00-31.00 inches or 960-1060 millibars. The Atlantic is our most accurate
marine barograph for the dollar. 10 1/2"L x 7 1/2"H x 6 5/8"D. BA2000
