MONTHLY CHARTS FOR RECORDING BAROMETER

Each recording barometer transcribes variations in atmospheric pressure onto a paper chart wrapped around its cylinder. This sheet covers the monthly charts, sold in packs of 50 sheets.

The paper used has been specially designed to work with NAUDET pens. Its composition allows for excellent ink absorption, without smudging or spreading, in order to obtain a fine, precise, and perfectly legible trace throughout the recording.

To choose the chart adapted to your device, simply follow these three steps:

• Choose the height of your cylinder (according to the models offered).
• Select the graduation in hectopascals (hPa). Monthly charts exist only in this unit of measurement.
• Choose the measurement scale corresponding to your device:
  • 966 to 1045 hPa
  • 943 to 1050 hPa

In case of doubt, our workshop is at your disposal to help you identify the chart corresponding to your device, regardless of its brand or age.
