Features & Applications:
The Tramex Concrete Moisture Meter and Relative Humidity Meter measures moisture content, relative humidity, temperature and dew point in concrete and gypsum flooring.
The CRH Moisture/RH meter
enables you to carry out 4 individual tests:
-
Measure non-destructively
and instantly the moisture content in concrete and gypsum flooring
-
Measure the relative
humidity, temperature and dew point within the floor slab or screed
using the
(below surface) In-situ method
-
Measure the relative
humidity, temperature and dew point above the surface of the floor
slab or screed using RH hood test methods
-
Measure the relative
humidity, temperature and dew point of the environment that the
floor is
being installed
In Moisture measuring mode it uses the principle of electrical
impedance measurement to give accurate non-destructive moisture readings
in concrete and gypsum floor screeds.
From Electrodes with special spring mounted probes on the base of the
instrument, a low frequency signal is transmitted into the material being
tested to measure the electrical impedance.
In Hygrometer mode it uses a solid state capacitive sensor RH probe
to give accurate and fast relative humidity and temperature readings.
While being easy and
uncomplicated to operate the CRH has a powerful micro controller, which
processes the information received and accurately calculates the moisture
content, relative humidity, temperature and dew point and displays it on
the clear digital display. It has a high capacity non-volatile memory chip
which stores and retains its data. This information can be recalled at any
time by scrolling and reading directly from the instrument's own display
or downloaded to a PC for storage and inclusion on spread sheet or report.
Excessive moisture in concrete floor slab and screeds can lead to a host
of problems in all types of floor coverings such as: adhesive degradation,
delaminating of the floor covering from the slab and within itself,
condensation, blistering, movement and deterioration of the covering. In
the case of wood flooring, excess moisture can lead to swelling, cupping
and movement of the wood which can lead to floor failure and even
structural damage. Excess moisture can also lead to mold, and mildew as
well as the emission of harmful vapors. Most of these problems can be
related to the floor covering being installed on a sub floor that is not
sufficiently dry. It is therefore important to insure that the floor
slab or screed is sufficiently dry enough to accept a covering.
