cheap hygrometer reliability?
    #1644784 - 06/19/03 02:37 PM (14 years, 9 months ago)

Quick question if anyone is up: How often do the cheap hygrometers found at reptile shops require calibration for accurate display of humidity? I am using perlite and a fishtank heater, and my hygrometer rarely goes above 85%. Could this be a error with the meter? The FAQ got me wondering...

The cheap-o ones are definitely not accurate at above like 80-85% RH. If you are looking for accuracy you need to move up to something like

Edmund Scientific Digital

most people on the shroomery don't use a real expensive one, though, and end up getting decent results. My friend had an analog hygrometer and it never went above 80%, while his digital was always reading above 90% (saturated for that model).

Sorry about not really giving you an answer other than "spend more money."

They are not reliable. At all.

they may not be reliable, but try the calibration method-my digi said 74 percent the next morning, so the test works, and so should the hygrometer you already have. once u get good at recognizing the air conditions and regulating everything, you'll never even look at the % and wont even need it.
