With a refined glass-and-brass presentation and a robust clockwork movement, it is ideal for professional meteorology, laboratories, educational settings, and collectors who value both precision and beauty. Choose the Barograph Naudet-Dourde at Stratosens.com for a reliable, elegant instrument that blends scientific accuracy with timeless design.

Key Benefits and Applications

• Continuous insight, at a glance — The pressure trace is recorded line by line, so trend changes, fronts, and daily cycles are visible instantly without electronics or screens.
• Proven mechanical reliability — A spring-driven clockwork drum and aneroid capsules provide dependable operation, ensuring uninterrupted records even in power‑limited environments.
• Professional‑grade readability — Crisp hectopascal grids and a fine recording pen create clean, high‑contrast traces that are easy to interpret and to digitise for reports.
• Elegant, showcase‑worthy build — A polished mechanism under a clear canopy turns precise measurement into a focal point, enhancing laboratories, observatories, classrooms, and reception areas.
• Flexible recording to match workflows — Interchangeable chart periods support short campaigns or long‑term studies, simplifying compliance, documentation, and audits.
• Versatile across sectors — Well‑suited to meteorology, research, HVAC and building diagnostics, museum displays, and quality assurance where traceable pressure history is essential.

Featured technical specifications

• Measurement principle — A stack of evacuated aneroid capsules mechanically amplifies pressure changes, with temperature compensation to stabilise the trace across typical indoor conditions.
• Pressure scale in SI units — Charts are graduated in hectopascals for direct reading in hPa, aligned with European and international standards.
• Range options — Common sea‑level ranges include 960–1060 hPa and 940–1040 hPa, supporting coastal to mid‑altitude installations with convenient zero and span adjustments.
• Recording system — A spring‑driven drum rotates at selectable periods such as 1 day, 7 days, or 31 days, writing with a fibre or felt‑tip pen on dedicated pressure charts for clear, archival‑quality records.
• Resolution and readability — Fine chart graduation enables practical readings to approximately 0.5 hPa by interpolation, with steady, low‑friction linkage for smooth tracing.
• Clockwork autonomy — Robust movement designed for routine weekly winding, maintaining stable rotation and consistent timekeeping for the selected chart period.
• Adjustment and calibration — Front‑accessible controls allow barometric setting and drift correction. The instrument is compatible with standard meteorological charts and calibration routines.
• Materials and finish — Precision brass mechanism on a hardwood or lacquered base under a transparent canopy, combining durability with a refined laboratory aesthetic.
• Consumables — Hectopascal chart packs for the chosen period and replaceable pens in assorted colours to enhance trace contrast and multi‑week comparability.
• Typical dimensions — Approximate footprint for display and bench use around 300 × 160 × 160 mm, with a balanced mass that remains stable during operation.
• Operating environment — Designed for indoor use in standard laboratory or office conditions, ensuring consistent performance and long service life with routine maintenance.
