No, it's not a mistake; the spec is obviously reasonable. However, some people have read it wrong. The operating temperature for the */device/* is -20 to +80; outside that range you get fried electronics (and a fried engineer, if you're holding it in your hand at the time). The */probe/*, however, is something else again. It's at the end of a wire and may easily be 100 degrees C warmer or colder than the device itself.
