Damage Restoration, Inspection/Surveying and Indoor Air Quality industries. To get the maximum benefit from the Elcometer 7410 Concrete Moisture Meter, it is suggested that you read this manual to familiarise yourself with the instrument and its capabilities, before undertaking any flooring tests.
ELCOMETER 7410 USER GUIDE HOW IT WORKS The Elcometer 7410 Concrete Moisture Meter detects and evaluates the moisture conditions within the cementitious slab or screed by non-destructively measuring the electrical impedance, which varies in proportion to the moisture content in the material under test.

HOLD button freezes needle on moving coil meter, to facilitate ease of recording readings. • If HOLD was selected prior to the Elcometer 7410 Concrete Moisture Meter automatically powering off, the frozen meter reading is digitally memorized and restored next time ON/OFF is selected.
Longer periods may be required in areas of high humidity or low temperature. During the drying period and prior to applying the floor covering, the floor should be regularly checked to monitor moisture content with the Elcometer 7410 Concrete Moisture Meter.
ELCOMETER 7410 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.
Press the Elcometer 7410 Concrete Moisture Meter directly onto the surface of the material being tested, having removed any dust or foreign matter from both the Elcometer 7410 Concrete Moisture Meter electrodes and the floor slab. Ensure that all of the electrode spring-loaded pins...

ELCOMETER 7410 USER GUIDE LIMITATIONS The Elcometer 7410 Concrete Moisture Meter will not detect or measure moisture through any electrically conductive materials including metal sheeting or cladding, many types of black EPDM rubber or wet surfaces. The Elcometer 7410 Concrete Moisture Meter is not suited for taking comparative readings in the concrete substrate through thick floor coverings such as wood.
ELCOMETER 7410 USER GUIDE It is therefore recommended that calibration of the Elcometer 7410 Concrete Moisture Meter should be checked and certified in accordance with the standards and/or protocols laid down by your industry (usually on an annual basis) by an authorized test provider. The name of your nearest test provider and estimate of cost is available on request.
