Product Overview: The Allen Datagraph System 725E-09 is an X-Y chart recorder that plots two analog input signals on paper in real time. It uses a pen-and-carriage mechanism to trace continuous curves, commonly applied in quality control, process monitoring, and laboratory testing where visual trend documentation is required. The unit features multiple voltage scales for both X and Y axes, typically calibrated in volts per inch. Key mechanical components include precision bearings, axis guide bars, and a pen drop mechanism controlled by timer circuitry.
