Monolog-2 Temperature and Humidity Logger
The Monolog 2 is a rugged compact temperature and humidity data logger designed for unattended operation over long periods of time. The instrument has been designed for hardware and software compatibility with the Windows PC environment. You can setup and interrogate the monolog very quickly and easily with a simple connection to your PC. The built in memory of the Monolog can hold up to 8184 data point pairs ( temperature and humidity ) which at the longest logging interval would represent almost one year of data. Yet the communication interface is so fast that you can download the data on to your PC in just 15 seconds

Windows Software
The software operates under Microsoft Windows (Win95/98/2000) and is very easy to use with a range of typical Windows style dialog boxes. You set up the logger by entering the start and stop time and the logging interval. You can build database files from the stored data and plot and save the information in table and graphical formats. The software supports multiple languages  including English and Spanish, French, German, Italian and Dutch.
