How to choose
Check the reference first. Similar-looking Dickson charts can have different time markings or measuring scales. C010 and C012 share a 0–100 printed scale but have different recording periods: 24 hours and 7 days respectively. Dickson lists them for both PW470 pressure and SL4100 temperature configurations, so confirm the reference printed on your chart. C022 and C026 are both 4-inch, 24-hour pressure charts, but their pressure ranges differ. C439 is a larger 8-inch, 7-day temperature chart and is not interchangeable with the 4-inch charts.
If your recorder uses another Dickson chart reference, see the Dickson chart paper selection guide or send us the reference printed on your existing chart for help identifying it.
