CONCRETE MOISTURE ENCOUNTER X5 USER GUIDE
13
CM (Carbide Method) Concrete Scale
The Concrete Moisture Encounter X5 gives readings of
0 to 4.3 on the CM Equivalent Concrete Scale. These are
approximated equivalent readings to the carbide test
method for concrete.
CM Anhydrite/Gypsum Scale
Equivalent reading to Carbide Method (CM) test for
Anhydrite, Hemi-hydrate, Gypsum and Calcium Sulphate
Screeds.
Gypsum Ref 0-12 Scale
Reference readings replicating measurements using
concrete scale on concrete & sand/cement floors/
screeds, for use on Gypsum floors/screeds.
Reference Scale
For the Reference scale the readings are comparative
from 0 to 99. The readings on the Reference scale are
not to be interpreted as a measurement of percentage
moisture content (%MC) or relative humidity (RH%). It
is not a relative humidity reading and it does not have
any linear correlation with Relative Humidity measure-
ments. This scale should be regarded as a comparative
or qualitative scale only. This reference scale is included
to facilitate comparative testing of different areas
where direct contact with the bare concrete surfaces
may not be possible due to some form of very thin coat-
ing or covering on the concrete, or additive in the con-
crete that could influence the readings. This scale is not
suitable for reading through thicker floor coverings such
as wood laminates etc. Readings from the Reference
scale are comparative only and of help in identifying
areas with moisture problems.
