Black Fibre Recording Pen
Black fibre barograph pen to fit traditional barograph arms. This is a disposable pen and therefore not intended for use with ink.
This fibre nib has two small dovetail grooves on the back so that it can be carefully slotted on to your existing metal barograph arm. The dovetail shape ensures it is held in place while in use.
If you are unsure which barograph pen or nib is suitable for your instrument please email a member of our team and weould be happy to suggest some options.
