CONCRETE MOISTURE ENCOUNTER 5 USER GUIDE
INTRODUCTION
Hi there! Thank you for trusting our brand and choosing
the Concrete Moisture Encounter CME5, from Tramex. It
is our goal to ensure that you are always happy with what
you bought from us, so please let us know if you have any
questions and rest assured, we are always here to help.
The Concrete Encounter utilises “state of the art” electronic
technology to provide the flooring industry with an accurate
and simple to use non-invasive handheld instrument for
non-destructive testing (NDT) of Moisture Content (MC) in
concrete and comparitive moisture readings in gypsum and
other floor screeds. It has been designed for the Flooring,
Water Damage Restoration, Inspection/Surveying and
Indoor Air Quality industries. To get the maximum benefit
from the Tramex Concrete Moisture Encounter CME5, it is
suggested that you read this manual to familiarize yourself
with the instrument and its capabilities, before undertaking
any flooring tests.
Why should a test be done?
Concrete floor slabs and screeds that are insufficiently
dry before flooring is posed, and high moisture content in
existing floor substrates can cause a host of costly flooring
system failures. Testing allows for confidence in a job well
done that meets manufacturer’s recommendations, official
standards and customer satisfaction.
When should a test be done ?
Concrete floor slabs and screeds should be tested regularly
during the drying period, to help evaluate and control the
drying process, and ensure that the substrate has reached
sufficient dryness before the floor covering is installed. For
the purpose of restoration, testing can be done on existing
concrete floors and screeds to evaluate the extent and
source of water damage, as well as controlling the drying
process.

HOW IT WORKS
The Concrete Moisture Encounter CME5 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. The
electrical impedance is measured by creating a low
frequency alternating electric field between the
electrodes on the base of the meter as illustrated in the
diagram below.

This field penetrates the material under test. A very
small alternating current flows through the field. The
Concrete Moisture Encounter CME5 detects this
current, determines its amplitude and converts it to a
moisture content value. By simply pressing the Concrete
Moisture Encounter CME5 down on the surface in
strategically chosen locations, instant readings can be
taken over a large area in the shortest possible time.
