How do handheld measuring devices and data loggers differ?
The fundamental difference between a manual measurement device and a data logger is that with the former, current values are measured ad hoc. With the latter, there is constant measurement including the storage of data which can be processed and analysed with special evaluation software.
A manual measurement device is practical when, for example, the temperature of food such as fish or meat in the refrigerator has to be measured. For running processes in production which must be completed under consistent conditions and allow only slight fluctuations, a data logger is the better and more reliable alternative. ebro manufactures PDF data loggers, for example, which process the recorded values graphically or numerically without special software so that they can be quickly reviewed on a monitor or as a print-out.
