Long Term Storage of HP 41C

[Giancarlo]

Hello,
I usually use prosorb or artsorb silicagel conditioned at 50% of relative humidity. I know that this represent a high value for metal preventing oxidation but i don’t have any info on the best relative humidity for electronical components.

I also think that calculators are emitting pollutants like any other modern (and not only modern) artifacts. For this reason i also use charcoals (a blend of them actually) to absorb these pollutants.

Not far in the future i will be able to measure some pollutants emitted by calculators. Unfortunately i won’t be able to do a full gas chromatography but i will be able to measure the VOCs emitted as whole including SOx and NOx.

Thanks

Giancarlo
