• Fibre nib to fit Lambrecht barographs and drum recorders. Each pen has two small dovetail grooves on the back so that it can be carefully slotted on to your existing drum recording arm. This fibre nib is a disposable pen and therefore not intended for use with our ink. Pen available as violet or black.

  If you are unsure which barograph pen or nib is suitable for your instrument please email a member of our team and we would be happy to suggest some options. Barograph pens may also be referred to as a barograph marker.
