Big Barograph

The big barograph is scientifically tested and proven. Under a high-quality plexiglass hood, it houses a measuring element a carefully aged 9-cans set and the 160 mm wide writing drum with clockwork. These precision parts ensure high resolution. There are four adjustable pressure ranges, each 106.7 hPa available. This is a high degree of flexibility allows for the Messortwahl.

A Barograph is a measuring device which records the timing of the air pressure on a paper covered with drum. The resulting curve is called "barogram". The evaluation of the barogram can give to the expert evidence of future weather development.

In particular, are often found on ships barograph. Barographs play in aviation, in particular glider, a role. Then, however, often spoken of a level recorder. Since the air pressure decreases with altitude is known, the altitude profile of the flight can be analyzed after landing.

The main features of the Great barographs are:

• network-independent and tamperproof
• broader writing drum (160 mm)
• Pressure measuring element with overload protection for transport to 2700 m altitude
•  9-fold membrane cans set
• corrosion-resistant, elastic material
• good measurement accuracy (± 0.2 hPa)
• long-term stability
• temperature compensated
• Reversible (1d - 7d) mechanical movement
• high reliability
• maintenance-free
