Chart recorder pen types include felt-tip, fiber-tip, and capillary designs. Felt-tip pens are the most common for general industrial use. Fiber-tip pens are preferred for precision work. Capillary pens are used in some older recorders.
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.
