Log Box-RHT
1. INTRODUCTION
LogBox-RHT-LCD is an electronic logger of temperature and relative humidity.
There are sensors that measure such data and values (data) obtained are displayed in
an LCD screen and stored in an electronic memory. Data can be later viewed and
analyzed on a PC where they can be opened in tabular and graphical forms. The
humidity output can be configured to display Relative Humidity values or the
temperature value of Dew Point.
The logger is supplied with LogChart-II software, which enables to set up the
logger operation mode. It is also used for visualization of collected data. Other
parameters such as end of measurements, logging interval, etc., are easily defined
through the LogChart-II software.
Measurements can be exported to and opened in other applications, such as
spreadsheet programs.
