1. Range of application:
●
This device is designed for quick-response measuring of moisture in buildings, on building sites etc..
●
The IM 15 allows moisture measurements in wood down to a depth of approx. 3 cm. and down to a depth of approx.
4 cm in concrete or wash floor. It is even able to detect moisture behind ceramic tiles or behind and under various
floor or wall coverings!
●
Simply place device on top of the surface to be measured - no injection into the mearusing object required!
2. Measuring and operating instructions
2.1.
Place bottom of indicator housing on a level part of the material to be measured. When measuring wood make
sure that measurements are carried out in accordance with its fibre direction - otherwise the values achieved
will be too low. For the measuring direction to be correct the wood fibre direction has to be parallel to the
indication (from left to right).
2.2.
The value indicated has to be evaluated depending on the material measured:
Concrete / wash floor
Indication
Moisture rating
0 ... 5
= dry
6 ... 9
= moist, normal degree of moisture
10 ...
= wet,
too wet for machining and/or finishing.
We recommend to wait till the material moisture has gone down to a standard of 6 to 9.
The IM 15 allows moisture measurements in concrete and wash floor down to a depth of approx. 4 cm.
Please note:
the moisture rating „dry“
is dependent on the measured material (different flagstones have a higher rating),
in this case the scale is relative to this point of origin.
Wood / fibre-reinforced polyester
Indication
Moisture rating
0 ... 3. ~ 0...12% :
dry, a varnish coating can be applied.
3 ... 6. ~ 12...20% :
air dry, if a varnish coating is to be applied make sure to use varnishes allwoing for
moisture in the ground material.
6 ... 11 ~ 20...30% :
wind dry,
finishing treatment is only possible using agents with a high moisture
permeability. Whenever several layers are to be applied we recommend to consider
drying
intervals.
11 ... . ~ 30% ... :
wet,
finishing is only possible with a paint system especially suitable for wet wood.
The IM 15 allows moisture measurements in wood down to a depth of approx. 3 cm.
