Just a drop of freezing liquid on the metal sensor contacts and who knows what that does to the readings? So if all the probes are reading 68* and the one I had to blow dust out of reads 50*, I have to let that one re-acclimate!

If the sensors electronics are insulated then it would be less an issue, no?

Well, I guess the all knowing rapidrh experts are not going to chime in on this one or my question about static electricity. sigh.......
