Question

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

Answer

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.
