I have 2 teledyne sensors. I put the little aluminum caps from oxycheq on them, but I don't think they do much. Its mostly to keep water/dirt/gunk off of them. My garage is fairly cool for the majority of the year.
I have had sensors last anywhere from a month (complained to TDL and got another) to >2 years (still going). I have 2 analyzers and only replace them when they die.
