Technical Note 163 Addressing PID Instruments Moisture Sensitivity

Preventing dirt and dust from entering the PID sensor is the best cure for moisture response. Make sure that all of the filters in the instrument are clean and effective. In dirty environments, it may be necessary to add an additional filter. However, under normal circumstances there should be no response to humidity with just the standard sintered metal and external filter installed.

Dealing with Dust on DSLR Sensors - Photo Review

Welded dust commonly occurs when a camera with dust on its sensor is moved between low and high humidity. Some of the particles absorb moisture, causing them to stick on the surface of the filter. Pollens are a common source of this type of dust, which requires more thorough sensor cleaning. Most dust spots are very small; too small to see with the naked eye. However, even a tiny speck of dust …
