Tramex Concrete Moisture Meter and Relative Humidity Meter is an advanced meter used for flooring.
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.
Features:
- Two versatile measuring modes, measures moisture content plus relative humidity, temperature and dew point with plug in RH probe
- User can switch between moisture meter and hygrometer modes
- Non-destructive moisture measurement
- Stores up to 900 recorded readings in 30 files
- Recorded readings can be recalled and displayed on dot matrix LCD
- Download recorded reading to pc for transfer to word processing or spread sheet
- Choice of scales to suit different types of floor slabs and screeds
- Operates on time proven impedance measurement principle
- Instant readings on clear LCD display
