Data Loggers (Measurement/Control and Processing Systems)

Data loggers are an essential component in data acquisition systems. They can scan a wide variety of measurement sensors, perform many programmed calculations, convert the data to other units of measurement, and store the data in memory. Data loggers can also transmit the data for analysis, sharing, and reporting, as well as control external devices.
