FOR RECORDING BAROMETER

Each barograph records atmospheric pressure variations on a paper chart wrapped around its cylinder. These charts are sold in packs of 100 sheets and are specially manufactured to ensure a clear, precise, and durable recording.

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

To choose the right chart for your barograph, simply follow three steps:

• Choose the height of your cylinder: 7, 9, or 11 cm.
• Select the graduation printed on your chart: hectopascals (hPa), millimeters of mercury (mmHg), or inches of mercury (inHg).
• Finally, choose the measurement scale corresponding to your device, i.e., the pressure range indicated on your barograph (for example, from 960 to 1050 hPa or from 970 to 1040 hPa).

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