Chart recorder pens are available in red, blue, green, black, and violet. Multi-pen recorders typically assign one colour per channel: red for channel 1, blue for channel 2, green for channel 3, and black for channel 4.
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.
