Chart recorder pen tip sizes range from 3mm to 15mm. The correct size depends on the recorder brand and model. This guide matches each size to the recorders that use it.
Selecting the correct chart recorder pen depends on the recorder brand and model, the required tip size, the ink colour, and the operating environment. Felt-tip pens are the standard choice for general industrial recording, while fiber-tip pens are preferred for clean, high-precision traces in pharmaceutical, laboratory, and food processing applications.
