Don't understand that. Nothing special about the site. May be a break in
my paste. Try http://www.onsetcomp.com/ and search for the U12 family.

They are fairly inexpensive data loggers but probably overkill unless you
are a compulsive tester/experimenter like me. So far I have only used it to
document tests of ice chests (the $60 Coleman Xtreme beat the heck out of
the $150 Iceytek and equaled the $400 Frigid Rigid) but once I start tuning
Rutu it will come in real handy.

A Hobo 12-012 data logger with internal temp and RH sensors and 2

I'm not real happy with this URL. When I accessed it, I got the

No warning or request. This is bad behaviour IMO. Can't do any harm to
this computer, but even so, I don't like it.

Why is an applet talking home to mommy?

Just why do they need to d/l an applet and run it to provide what on
the face of it is a pretty simple Web page?

I was interested because we make extensive use of dataloggers. The ones
we use are dataTakers - http://www.datataker.com/. These are NOT cheap,
but we run them in Antarctica and on icebreakers for months at a
stretch unattended. I'd like to find something cheaper, but my
electronics engineers express a total lack of faith in USB devices when
run time extends to months straight. Too many bad experiences.

Heh --- compulsive. I use one of their devices (dedicated
temp and humidity) to monitor a wine cellar, recording
conditions every few minutes. They make a shuttle that
lets you collect data from the logger and carry it to
the PC for downloading. That way you don't have to dismount
the logger and take it to the computer for downloading.

Actually Practical sailor beat me to it. They used a much simpler melt test
but their results were the same as mine. Just shows you can do the same
thing with $10 worth of ice as I did with $10 worth of ice AND $150 worth of
electronics. :-)
