If accurate humidity is important, get a calibrated, traceable hygrometer.

I used a sling hygrometer in the bad old days, to record conditions when using sextants, transits, and tellurometers for hydrographic surveys.

I don't know which one you used, but the old ones I've seen only make measurements. I'm guessing that you recorded the raw (dry/wet) data and calculated results on paper.
I have the Ruggard 30L, purchased from B&H on a sale. On a normal day, humidity is around 65% in the SF Bay Area...probably don't need the cabinet, but I figure it's a good place to store expensive items, keeps them from getting dusty, and removes any extra humidity.
