What is the rehydration procedure to recover the sensor from exposure to organic solvents or high humidity environments?


Typically, initial accuracy can be recovered by baking the sensor at 125 °C for 12 hours followed by ~2 days storage period in normal ambient conditions with ~50%RH. High RH exposure (i.e., 75% RH for 12 hours) will accelerate the post-bake recovery, but, after high RH exposure, approximately two days at normal RH is still recommended for the device to fully recover its accuracy. The bake/hydrate procedure can be found in AN607 along with further details.
