CME4-EU 07/13
PRODUCT DESIGN HOW IT WORKS
The CME4 Concrete Encounter detects and
evaluates the moisture conditions within the
slab or screed by non-destructively measuring
the electrical impedance. A low frequency
electronic signal is transmitted into the material
under test via the electrodes in the base of the
instrument. The strength of this signal varies in
proportion to the amount of moisture present in
the material. The CME4 determines the strength
of the current and converts this to a moisture
content value for concrete slabs and a compara-
tive value for other cementitious floor screeds,
displayed on a large clear analog dial.
OPERATING PROCEDURE
To carry out tests simply brush any dust from a
smooth area of concrete and also from the
electrodes, switch on the Concrete Encounter
CME4 and place it firmly onto the surface, fully
compressing the spring-loaded, signal-enhancing
contacts on the base. Read the moisture content
from the clear analog dial.
The CME4 is calibrated to give percentage
moisture content readings on clean, bare dust free
concrete floor slabs, with a depth of penetration of
approx. ¾". Readings taken on concrete slabs
through paint, coatings, adhesives or other
materials on the surface should be regarded as
qualitative or comparative and not quantitative.
