Environmental monitoring devices and software are common elements used by biologists, ecologists, foresters, and the like. Try asking a professor at your local university. I have seen a few items like you're describing in Forestry Suppliers catalog or Ben Meadows catalog. I imagine checking for environmental education materials might turn up some cheaper answers, as well. Good luck.

Is this something free or is it a paid program. There are a number of free programs that do a good job of clearing temporary files, cache, etc. I'd steer clear of most of these types of programs. I would recommend CCleaner. Used at the default settings it does a nice job. Download the FREE version which does a nice job. Here is a link that might be useful: CCleaner

As far as functionality is concerned, 2012 will meet my needs just fine since I'm not downloading stuff. I am currently using it after all and it works just fine for me. The only reason I wanted to upgrade is that my version is completely unsupported now. At least if I could find a copy of 2017 I'd get software updates for the next few years. Microsoft is constantly putting out Windows updates and I'm always worried that one of them will cause some sort of issue with 2012 and there will be no patch coming from Intuit. Besides, if I'm going to avoid the subscription model as long as possible it just seems my best bet would be on the very latest version that is pre-subscription model.
