They include a real-time SD memory card data logger (1 to 16GB capacity) built-in clock and calendar and real time data recorder. Auto sampling time can be set from 1 to 3,600 seconds and the user can also log data manually. These real-time data loggers save measured temperature data, along with the time information (year, month, date, minute, second) into the SD memory card. Data can subsequently be downloaded to Excel for analysis.
