Barograph nib, standard - (individually tested)
These are the traditional type of wet ink nibs often used on old barographs. We can not be certain they fit any arm but we use them on practically all old barographs using one pen. If the arm has corroded or is just wider than normal then sometimes a new arm or some alteration to what you have may be needed. Generally a competent person shoudl be able to open the tangs of the nib a little and slide over the arm, the nib is then clasped on using a pair of pliers carefully tho close the tangs around the arm. Made from stainless steel so shoudl last many years if not damaged.

Fibre nib for Barigo Barographs, often will fit traditional barographs but there is no guarantee as pen arms vary in size, it is light weight and lasts quite a while. Most times the arm could be adapted to fit or carefully glued on if necessary. Size of pen is approx 21mm long by 4mm square with protruding angled fibre nib 5mm, teh back has a raised dovetail slot approx 8mm long x 2mm tapering to 1.5mm. These are disposable and not intened for use with our ink. They come in a sealed pouch to keep longer so once opened no return possible of course. If uncertain of fit then send us ONE picture of the barograph and an e-mail covering what you are looking for - we might be able to suggest possibilities.

Long reach barograph nib for use with twin recording instruments, normall Baro-Thermomgraph so pens do not foul each other. So if you have two instrukmenst recording on teh same chart you may require a short standard nib and a long nib like this set at about 6 or 12 hours difference (what suits the instrument) so they do not hit each other.

Barograph replacement blank arm, aluminium, undrilled, length 8"
Gemerally for old barographs but will require drilling to suit.
The ink used on barograph is corrosive and often attacks aluminium, so keeping the end clean prolonges the live of the arm. Latter instrumenst introduced stainless steel arms for obvious reasons but most old barographs used aluminium as light weight, If the arm of your barogrpah has a wide end where the nib fits it may have been shortened over the years and could be in need of a new arm.
If you wish us to make the arm for you contact us first.
