Paper material change: Sato discontinued the 7210-60 / C241540 and 7210-62 / C1681540 clean-paper charts and introduced the ordinary-paper alternatives 7210-80 / NTH011540 and 7210-82 / NTH071540 from January 2025. If your application requires clean paper, confirm the material requirement before ordering.
If your existing chart carries an SKN/C marking, 7210-64 or another older reference, send us a clear photograph of the complete code and printed scale so we can check the appropriate alternative.
