METALLIC PEN
FOR BAROGRAPH

Manufactured, adjusted, and checked in our workshop, this metal nib allows for a precise and regular trace on your barograph's charts.

Compatible with most barographs and recording instruments, regardless of their brand or era, it operates on the principle of capillarity: ink is progressively deposited on the chart to ensure continuous and perfectly legible recording.

Each nib is carefully adjusted before shipping to guarantee quality writing from the moment it is put into service.

For best performance, we recommend using our special Naudet ink, specifically formulated not to dry on contact with air. A single drop is usually enough for approximately one week of use.

To preserve your nib, it is recommended not to alter its spacing. For cleaning, ink residues can be removed using denatured alcohol.
