Another thing to consider is your ceiling. Controlling humidity in a room with smooth sealed material on the ceiling will work better than fiberglass ceiling tiles.

thanks for all the replies guys, this really helped me a lot

I forgot absolutely that the device is "switchable" samsung, thanks :)

"Please note that dry air with less than 40 % relative humidity increases the risk of your weighing vessel or the sample to become electrostatically charged to cause weighing errors arising through the electrostatic forces that act between the weighing sample and the surroundings."

yeah, that's the main reason why we make the effort
There are other reasons as well for maintaining a certain humidity level in the room. e.g. in our case, it is mandatory to store the cast cement samples in lab atmosphere with average 60% RH & 27 degree C.

thanks for all the replies again :)

We got some Sharp KC6500 humidifier to the room, and it has the ionisation option, so I started to wonder, cos it is all about the charges (+), and all the humidity is to help prevent them, but the ionisation does the same

So the question is - is there really a need to humidify the air? does ionisation do the trick? could someone explain the mess I have right now in my mind?
