Recording ink

for mechanical recorders

Octopus Fluids® Recording inks for barographs and other mechanical recorders

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. You can order smaller quantities of our inks online here. If you need larger quantities (5 L containers or more) for your company, please call +49 (0) 351 7968925 or send an e-mail to
