1100 Series Plotmatic Recorder

The 1100 Series Plotmatic Recorder line from Allen Datagraph System LLC consists of analog XY plotters used for graphical recording of voltage signals. These units capture two-channel voltage inputs onto chart paper using a pen-and-string mechanical positioning system.

The series includes the Datagraph Recorder Type M XY (Model 1144), which offers selectable voltage ranges from 0.025V to 10V on both the X and Y axes, along with a time-based sweep mode for strip chart operation. These recorders are designed for applications requiring the plotting of two-channel voltage inputs, typically in the 0–5V or 0–10V range.
