Make your own Digital Hygrometer

[Gazzer]

Do those units come pre calibrated??

I presume so but thats why I placed it side by side with another one that I have been using. Ball version.

 

[Peter]

Bought one just incasey. Never needed one yet and hopefully don't in the near future either.

 

[Ian]

All my bits have arrived :hurray:

 

[Ian]

Neale, what did you use to route out the back of the sponge? It looks very neat.

 

[Gazzer]

A woodwork router

Oh, I don't own one of those. Looks like I'll have to be super carful with a craft knife.

 

[Gazzer]

Rotozip ?

 

[White Room]

Dremel...or a cordless drill.

 

[Ian]

I'll find a way, I do have a dremel or maybe the Fein will do it. Do the routes have to be a certain depth do you think? Or is it just an area for the air to gather?

 

[Gazzer]

25mm side walls and 25mm deep

If you are still struggling I can send you one I made earlier ....:lol:

Not had chance to look at it yet, a job for Sunday I reckon. I'm sure I can manage to cut a couple of pieces of sponge :lol: I've got 4 chances to make 2 hygrometers :lol:

Are your hygrometers tried and tested yet Bri ?

Haven't used them yet, have 3 floors to do starting in March, that'll be the first chance I get to use them.

 

[judge]

I wonder if Neals patened them yet.Think im gonna make a few of my own before he does ...lol:smilewinkgrin:

 

[Gazzer]

Lol. Mine seem fine. All within 3% of each other.

 

[Peter]

Is the smaller inner square necessary Neale?

 

[Swindiff]

Is there anything to stop you putting these on the floor and then just taping some clear plastic over them creating an airtight seal to the screed?

 

[Swindiff]

and is the hygrometer you posted any better than this one at a fraction of the price?
