Choosing the right chart recorder pen tip size is essential for a clean trace and accurate recording. ABB C1900 and Kent/Taylor 1900 ERC use 6mm pens; ABB C1914 and Yokogawa MR-180 use 8mm; Honeywell DR4500 and Partlow MRC 7000 use 10mm; Eurotherm uses 10mm; Taylor 90J/91J use 3mm.
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.
