Recording ink, barograph ink for barographs, hydrographs or seismographs
Our recording ink, or barograph ink, is perfect for aficionados of mechanical barographs, hydrographs or seismographs and other mechanical recording devices.
The development of these inks focused on the balance between an appropriate drying time and smooth lines. As recording ink, it stays moist for a long time inside the barograph and on the fibre pen. It starts drying more quickly only when it gets in contact with the paper.
Our inks for barographs, hydrographs and seismographs are available in black, blue, red, green, and violet.
