When checking your thermometers for accuracy remember that altitude does effect the boiling point of water. The boiling point for water is 212* at sea level. For every increase of 500 ft. in altitude, the boiling point of water will decrease by 1*. This may not seem as much, but at some higher altitudes there willl be a difference of several degrees. I'm at 187 ft. above sea level, but I can't split degrees on my thermometer so my boiling point of water is 211*. Just don't think that the thermometer is off by so many degrees without considering the altitude. I know this may be overkill, but some techies will enjoy it.
