Make your own Digital Hygrometer

[Gazzer]

Purchase Digital Hygrometer from Ebay , while you are there you may as well get the 50mm foam too.....I bought 4 units and one piece of High density foam which was enough to make 4 units.

Cut foam to 200mm square

Then route out the rear ,,,,,You can easily make the correct size round hole with a silicone sealant tube, just push and twist it through the foam.

Insert the Hygrometer unit which is a push fit int the round hole

I have had all 5 units on in the same area in my house and there was only a 1% difference .
Total cost ????.....£22 ! per unit.

[Lee@emctiles]

So Neale, do they read quite accurately?

 

[Gazzer]

As accurate as the Ball version, its the same unit !

On the dense foam could you use the kingspan type stuff..

I was gonna used some Marmox board I had lying around, honest anser I dont know but dont see why not as long as it creates an air tight seal to the floor by using the butyl tape or silicone sealant or decorators caulk.

 

[Ian]

Would you still stick the foam to the screed, or do you think it would read correctly just placed on top?

Lol, question answered!

 

[Gazzer]

Yes Bri you still need an air tight seal.

 

[Ian]

I think I might order a couple at that price, I won't have to borrow one anymore!

 

[Lee@emctiles]

I will swap you some bags of Anhyfix for a couple!

You know it makes sense Rodney.....ermm Bri !

 

[Ian]

Just bought 2 and a piece of the foam, £50 well spent. There's only 1 unit left now from that seller.

 

[Gazzer]

You could always pay £30 just for the box.....now call me tight ! :lol:

[Gazzer]

Simple enough to try Mark but I like to test it along side a known good unit

He's probably the one selling the foam on ebay, all scraps dragged out of skips....

 

[Ajax123]

Do those units come pre calibrated??

 

[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.
