The ABUS LogBox–RHT is an electronic logger for Relative Humidity and Temperature. There are sensors that measure such data and store them in an electronic memory. 
Data can be later viewed and analysed on a PC where they can be opened in tabular and graphical forms. 

The logger is supplied with Logchart-II software, which enables to set up the logger operation mode. It is also used for data visualization. Other parameters such as end of measurements, logging interval, etc., are easily selected through the LogChart-II software. 

Measurements can be exported to and opened in other applications, such as spreadsheet programs.
