Description
HP Hewlett Packard 78572B Thermal Chart Recorder Stylus ECG Strip 100-240V
The HP 78572B is a benchtop thermal stylus chart recorder made by Hewlett-Packard. It uses a heated stylus to mark on heat-sensitive roll paper, producing a continuous time-stamped trace without ink, toner, or ribbon. The unit features front-panel controls for stylus heat adjustment, variable chart speed, and a built-in date and time stamp function with settings for year, month, day, hour, and minute.

Applications
The HP 78572B is a strip chart recorder from the 1980s era of Hewlett-Packard medical and laboratory instrumentation. Strip chart recorders of this type were used to produce a continuous paper trace of an analog signal over time — most commonly in clinical and physiological monitoring applications such as electrocardiography (ECG/EKG), patient vital signs trending, and other biomedical signal recording. The thermal stylus design eliminated the need for ink pens or ribbon, reducing maintenance and improving reliability in clinical environments. HP produced a range of compatible recorders and patient monitors during this period, and the 78572B was designed to integrate with HP's bedside monitoring and cardiology systems. Today, units like this are sought by biomedical engineers for legacy system support, vintage medical equipment collectors, and labs needing a straightforward analog chart recording solution. The selectable 100–240V input makes it compatible with international power systems.
