74 Darton Thermograph Chart

The Darton Chart No. 74 is a thermograph chart designed for recording temperature over a 24-hour period, with a measuring range of 10-110˚F. Printed in red, each chart measures 297mm x 93mm, and packs contain 100 charts.

These traditional non-adhesive charts are ideal for use in recording drums that feature a clip to secure the chart in place. For drums without a clip, it is recommended to use chart tape to hold the sheets securely.
