Special Usings, Recommendation 

 

Measuring moisture in 

caravans, trailers, moble homes 

 

For this using we are producing instrumenst with shorted sensors as showed in the picture nearby. 
With such sensors measurements can be made in edges without being influeced through the adjoined 
wall.  

We recommend the material settoing HD5(H) (code 31) 

measurement: 

 

1. 

1. 

make a reference measurement at a dry place   

2. 

2. 

change the material setting til the instrument shows approx. 5%   

3. 

3. 

now different similar places can be checked for higher moisture content.   

 

Attention: 

 

Frames may also causes higher moisture readings. Therefore the instrument also can be used 
to detect frames. 

 

Moisture measurement in plastic boates: 

 

Caused through Osmose plastic boates can get blisters below the water line. At thsi blistes the moisture in the 
plastic rises up. Befor starting a repair such parts must be completely dry. To measure this we recommend to 
select the wood material group, material no. 0. The surface of the place where you need to measure must be dry!   

Measurement:  

1.

 

1. 

take a reference measurement above the water line   

2.

 

2. 

select the material no. till the reading is approx 10%   

3.

 

3. 

now you can measure at similar places to see the moisture 

differences.
