• Dimensions: 265mm x 170mm x 175mm
• Weight: 3100 grams
• Casing: High-gloss polished mahogany box
• Finish: High-gloss polished gold-plated brass parts
• Mechanism: 8-pressure can barometer for accurate air pressure recording
• Mechanism: Quartz battery system
• Writing instrument: Durable scriber for long-term use
• Registration paper: Including diagram paper for 1 year, choice between hPa or inch scale

• Moisture-free installation: Always place the barograph in a dry environment. Moisture can damage the mechanism and affect the accuracy of the measurements.

• Avoid direct sunlight: Keep the barograph out of direct sunlight. Excessive heat and UV radiation can damage both the wood and the gold-plated brass finish, and blur the recording diagram.

Cleaning the cabinet: Use a soft, dry cloth to clean the high-gloss mahogany cabinet and the gold-plated parts. Avoid cleaning agents, as they can damage the wood and metal surfaces.

• Installing and removing diagram paper: Replace the paper with clean, dry hands to prevent oil or dirt from affecting the paper or writing instruments.

• Phaser scriber maintenance: Check the writing performance regularly and store the phaser scriber in a dry and dust-free place. Always use clean hands when handling to ensure accuracy and longevity.

• Battery maintenance: Replace the battery in a timely manner to ensure uninterrupted operation of the drum drive. Ensure that no corrosion occurs around the battery connection points.

• Routine checks: Check the mechanism periodically and ensure all moving parts operate smoothly. Consult the manual for specific maintenance instructions and follow them carefully.

• What is a barograph?
A barograph is a precision barometer with a recording arm that records air pressure fluctuations on a rotating paper roll. This allows for monitoring and analyzing changes in air pressure over time.

• What does a barograph measure?
A barograph measures air pressure and records it on paper. This makes it ideal for maritime weather forecasting and navigation, where you can observe trends and patterns in atmospheric pressure.

What is the difference between a barograph and a barometer?
A barograph measures and records air pressure changes on paper, while a barometer only displays the current air pressure. This makes the barograph suitable for users who want a historical overview of pressure changes.

How often should I replace the paper in my barograph?
This barograph comes with a year's worth of paper. Depending on your model, you'll either replace a yearly roll once a year or individual weekly sheets weekly. Consult the manual to see which system your barograph uses.

How do I maintain the phaser scriber of my barograph?
Keep the phaser scriber in a dry place, away from direct sunlight, and install or remove it with clean hands to ensure long life and consistent recording.
