The Meteograf is the best electronic barograph that we have seen. Generally speaking, mechanical models are not suitable for boat use because platform movement causes inertial pen movement apart from pressure changes. Electronic barographs are not subject to this problem.
How it works
A scriber point engraves the fluctuating pressure onto the reverse side of the waxed indicating paper roll. The resulting mark is immediately visible in the main display window as a clear, clean, linear indication. Because the scriber is behind the paper, a new roll can be loaded as easily as film into a camera. The LCD window displays numeric pressure, and has a zoom function to observe short-term changes which would be indiscernable on the main display.
The chart and battery need replacement only once per year; ink free recording – no pen to replace; very compact dimensions (6 1/2″W x 5 3/4″H x 1 3/8″D); all internal contacts are gold-plated; 4-day display; no need for marine damping; aural and visual alarms signal dangerous pressure changes, and are programmable.
The Meteograf easily mounts to a vertical surface using velcro, or can be free standing. There is also a choice of flush-mount panels in chrome or matte black. Includes one roll of chart paper (mb). Power is from one C size battery, both good for a year. SW 2 lb.
