    Just kidding.......Pour a tablespoonful of salt in a small container, preferably a container lid. Put a few drops of water in the salt just to moist it and not dissolve it. Next, place the container of moist salt, together with your hygrometer, in a see-through container or ziploc bag. Seal the container. Leave it aside for few hours, say about 4 hours. Check and see the reading on your meter. An accurate meter should read 75% or close to it as the humidity inside the container with moist salt always maintains at 75%. Got it from somewhere on the net......kekeke......but my meter showed between 74 - 76% all the time while inside the ziploc bag. Once it was brought out, it shot up to 85%.

    This is strange. I encounter totally the opposite. My Radioshack digital hygrometer responds immediately and very fast. The slow one is the analog one.

    If you want to buy hygrometer, I suggest SLT, the third floor, next to the escalator.

    There are so many types there. For me, I paid almost $60 for it. It can read two different RH readings, it has a max/min for the day.

    I find it extremely useful.
