Main Question or Discussion Point

Q :
1 Materials that can control moisture in themselves ? (I want to know which material has properties similar to this.)
2 Materials that know moisture content without measuring ? (I want to know which material has properties similar to this.)
3 The material has a uniform moisture distribution ? (I want to know which material has properties similar to this.)


Please give an example to me

Hello Other, :wink:

What have you come up with in your search so far ?
Or is throwing the question at PF your first step ? (It shouldn't be)

Might this be homework ?

Please provide more detail about what you are trying to do. These questions are very vague.

I want to do a project on moisture measuring materials. Therefore, now need to try to find a material with a certain moisture content to reference the measurements.

I'm sorry isn't homwork. I just want to know, maybe someone in here can answer this question

Can you give us more context? Solid, liquid, gas materials? Destructive/non-destructive, remote/contact, batch/continuous sensing?

Moisture content in solid materials.
Is the measurement of moisture content in materials using methods other than drying.
Can you give an example if you know?

Assuming the material is open celled then you could weigh it and then dry it out and weigh it again. That would be a reliable but cumbersome way. I have bought a few different soil dampness meters and they are not very convincing.

Thread re-opened after merging two duplicate threads in different forums.

@Another -- Please do not create multiple threads on the same question. Also, you must show your effort in this thread, or it will be closed. And despite your assurance that this is not for schoolwork, the thread may end up getting moved to the Homework forums at some point. Thank you.

Can you explain more about the material is open celled

I mean that there is a pathway for the water to get out - like a washing sponge, as opposed to the sponge used in non-pneumatic tyres. But I now realise that my comment is garbage in the context of the OP.

If you don't want to 'destroy' the material by removing the water, you could always take a representative sample and analyse that, destructively. It all depends on how much you know about the material. You could look for EM absorption. Loads of methods come to mind but the context has to be 'revealed'.
