I recommend the Hanwell Hobo systems, they are more flexible and save 
the data digitally. The first one you posted doesn't look like it 
records anything. Hanwells can start off a bit pricey (though less 
than the price of a hydrothermagraph) and can be upgraded later. I 
like the U series loggers.
