128 Darton Baro-Thermograph Chart

Darton Chart No. 128 is a baro-thermograph chart designed for recording pressure and temperature over a 7 day period. Printed in red and measuring 302mm x 92mm, each pack contains 100 charts, providing two year's worth of monitoring.

Traditional non-adhesive baro-thermograph charts ideal for recording drums that have a clip to hold the chart in place. If your drum recorder does not have a clip we suggest using our chart tape to hold the sheets in place.
