Question hygrometer
<< < (4/5) > >>
Ysjoelfir:
To be a bit more serious: thats also an option. I use one of those in the lab and they don't differ that much from my Lambrecht 252 - only difference was the price and that the cheap one is easier to read. Sort of.
But since micksmelanie is very concerned about longevity an analog one might be the better choice, one like that, used eg. in humidors to keep the moisture of the cigarrs constant comes to mind:

They're cheap and work fine.

I already had this hygrometer but it didn't have this cable, is this version with a cable better than the version without the cable? I will put it in the bedroom and living room
steve30:
The cable just means that you can measure the humidity in one place, and put the display in another place.

For example, put the sensor in a box, and have the display visible outside the box.

There will be no difference in accuracy.

digital and needle hygrometer have the same precision?

Which bit of steve30's answer did you not understand?
