Paperless recorders monitor and log information about a process. Typically this will be temperature, pressure or RH etc; but any parameter that can be converted to a suitable electrical signal can be recorded.
A paperless recorder is differentiated from a data logger by its full color display. This allows the recorder to mimic the look and function of a traditional chart recorder, showing a graphical view of the data over time.
Other views, such as bar graphs, process views and reports may also be available. Paperless recorders usually offer on-screen analysis of the data, but recordings can also be transferred to a PC for analysis and storage. Paperless Recorders include a battery backed-up real time clock.
