There are 3 main recorder types. First type uses a strip of paper, it’s more easy to understand and use, but it occupies a lot of space. The second type has a circular record chart, which is essentially a disk of paper that rotates under pens. It must be replaced frequently, but they are smaller in size and are usually used to display information. The third type has a roll of paper, they serve for much longer, but they are fully embedded in a frame and are more often used for the latter analysis of a specific parameter.

Chart recorders may be useful in various situations, and are frequently applied at power plants, factories, meteorological tracking stations and similar industries. MegaDepot provides a great choice of chart recording devices manufactured by the best brands for the best prices you can find.
