What are the best digital hygrometer brands? i have a chinese compact hygrometer and a xiaomi hygrometer both use CR2032 battery why some hygrometers use AAA battery?

I am looking for a good cheap and highly accurate hygrometer to measure the humidity in my room

these hygrometers that I have show 60% while my air dehumidifier shows 35% and I don't know what the truth is

Purchase one that has a calibration certificate with it.

On another tack, why are you so concerned over the humidity levels that you need to know to a 'precision' level?

Which model and brand has calibration certificate? which models are not too expensive?

I intend to keep the humidity closer to 50% to avoid oxidation of electronic boards but if the humidity is really 35% it will dry out plastic and rubber

I'm not your mother nor your nanny. Do your own research. Sellers will indicate if they can provide a calibration certificate and also tell you the cost.

If YOU are incapable of doing the research then have you heard of Google?
