Humidity testing the shop hygrometer

If you remember the previous post about humidity,  recall the plastic pouch with special crystals that control the humidity in the pouch at 32% rh?

After 24 hours in the pouch , the hygrometer reads…. 31%.  Pretty accurate.  The least accurate was the “Accurite” unit.  I’m renaming it “Accuwrong”.
