CME4
CONCRETE MOISTURE ENCOUNTER
Screeds and concrete
floors must be dry before
a floor covering is
installed.
Don't take risks with
excess moisture!
Moisture test before you
install a floor covering.

MOISTURE
METER
FOR CONCRETE
Instant and non-destructive tests per ASTM F2659 with the Tramex CME4, a
non-invasive handheld electronic instrument used for testing moisture condi-
tions in concrete slabs and giving comparative readings in other cementitious
floor screeds. Precise and easy to use, the CME4 allows the user to make
multiple tests over a large area in the shortest possible time.
Product order code: CME4
ASTM F2659

FEATURES
Clear easy-to-read analog dial.
No need to probe, drill or
mechanically damage the surface.
Instant and precise readings to a
depth of approx.
¾"
into the slab.
Non-destructive in operation.
Hold function "freezes" meter
reading when inspecting areas
where the meter face is not visible,
and for easy recording of data.
Reproducible results.
Spring-loaded contact pins
compensate for uneven concrete
and boost signal penetration.

USER GUIDE INSTRUMENT FEATURES A diagram of the instrument face with brief notes on the push button controls and LED indicators is shown below. 84mm Moving coil meter. 2 = Hold – flashing LED. 3 = Power ON Led. 4 = Power ON/OFF button. 5 = Hold button. - Page 8 USER GUIDE INSTRUMENT FEATURES Your Concrete Encounter CME 4 employs advanced analog and digital technology to enable the incorporation of many new features which greatly extend the capability of the instrument. Two simple push button controls, ON/OFF and HOLD. Concrete moisture readings, 0% to 6%, are displayed on a clear easy to read moving coil meter with linear scale.
- Page 9 USER GUIDE HOLD button freezes needle on moving coil meter, to facilitate ease of recording readings. If HOLD was selected prior to the CME4 automatically powering off, the frozen meter reading is digitally memorized and restored next time ON/OFF is selected.

USER GUIDE WORKING WITH THE CME4 Drying time for concrete floors and screeds Concrete floors and screeds must be allowed to dry to an adequate level before the installation of floor coverings or application of coatings. Manufacturers of such systems generally require moisture testing to be performed before installation or use on a floor slab. -
Page 11: Pre-Test Conditioning And Preparation
USER GUIDE Pre-test conditioning and preparation For best and most accurate results, to allow for an accurate reflection of the amount of moisture present and moisture movement in the slab during normal operating conditions: Artificial heating or drying equipment should be turned off at least 96 hours before final readings are taken. -

The upper LED light flashes slowly indicating HOLD is If the CME4 is powered off while on HOLD, the frozen reading is digitally memorized and restored when powered on again.
- Page 14 NOTE The CME4 is calibrated to give percentage moisture content readings on a clean, bare dust free concrete floor slab, therefore readings taken on concrete slabs through paint, coating, adhesives or other materials on the surface of the slab should be regarded as qualitative or comparative and not quantitative.
