I was thinking about ordering one of these: 
http://store.qkits.com/moreinfo.cfm/vk011 for measuring temperature inside, 
outside, and wherever. I think tracking the temperature as I take long term 
measurements would be a good idea.

I was wondering which is best: measuring the room temperature that the 
equipment is in, or measuring the temperature of the equipment itself. If 
the equipment, which spot? Some parts are much hotter than others (heatsinks 
for example). If room temperature, where in the room? The corner with all 
the equipment is warmer.

As for outside temperature, how should I house the sensor to protect it from 
the elements, yet not interfere with its measuring capability? For example, 
if I were to encase a sensor in epoxy, that would certainly cause a delay 
between the actual temperature change and when it was measured by the 

Any other thoughts on the topic also welcome.
