Bev Would there be a commercial market for such indicators (say 1 M units/year)? If so, would you want it to show a dunking in water (how long reaction time at what temperature?) or exposure to high humidity (what RH threshold at what temperature and reaction time?). I can envisage several types of, say, 1210 pseudo-components with a colour band which would change permanently (short of deliberate tampering). They might not like aqueous cleaning though :-( Also, would you prefer them to operate only in power-on conditions or at all times (service or storage)?
