A chart recorder is actually a device that reads and then provides the output on a piece of paper that is rolling. The markings on the paper are done with one pen or more than one pen of different colors for the creation of a distinguishing effect as and when required. For instance, if the chart recorder measures seismic activity then two different colored pens might be used for the measurement of velocities and types of waves. Taking into consideration the operation, the chart recorders are available in three basic varieties that are electronic, mechanical, and electromechanical. The chart recorders have a wide range of applications. Now, at this point in time, the users tend to get confused about the selection of the chart recorder. The task would be easier if the following points are kept in mind at the time of selection of the chart recorders.
