When plugged into a PC’s USB port, this sensor measures temperature and relative humidity from -20° to +70°C (-4° to +158°F) and 0 to 100%RH. EasyLog RT software allows the PC to display temperature, humidity and dew point (the temperature at which water vapour present in the air begins to condense) data in real-time and saves it to a file which can store up to 7 days' worth of data for graphing, printing and exporting to other applications.

This data logger is not compatible with the DataPad.
