It's "non-reversible" which I'm guessing means the color change is
triggered by a one-way chemical reaction that's triggered at various
temperatures. I don't know how durable these things are -- e.g., how
long the things remain "reactive" vs. become inert, etc. I'm sure it's
something that's easily researched with a call to the manufacturer to
see if it meets your requirements.
Similarly, Telatemp's "coldsnap" recorders seem to work for the other
side of temperature measurement:

I know I've seen something in the past, but I just can't remember what it was called, to find it again. So far, all I'm seeing are min-max recording thermometers, mostly devices with batteries, and therefore a short life, intended to track the handling of a shipped product from one sender to one recipient - a matter of days or weeks, at most. I'm looking for something that the service people can view when they open a "broken" product that has been RMA'd possibly 5 years after it was sold and see that it was once subjected to -35 degrees Celsius (or +150 or whatever).
