Information about the product
Product description
Using the CRH measuring chamber CRH100 together with the
multifunction measuring meterT3000 as well as the climate
sensor TS230SDI allows you to measure the residual humidity
in mineral screeds according to the CRH method and thus to
check the mineral screed's readiness for covering.
CRH measuring method
When using the CRH measurement method, the corresponding
relative humidity(CRH) of mineral screeds is determined with a
test method suitable for construction sites and crafts. The
corresponding relative humidity is the relative humidity in
percent[%RH] that is measured in the air space via a mortar
sample of the material in a state of equilibrium. The measuring
method was co-developed by the Technical Commission on
Construction Adhesives(TKB) and confirmed in extensive
interlaboratory tests with experts.
The great advantage of this measurement method is that
general, material-independent statements on the moisture
condition of mineral screeds can be made immediately after the
measurement. This increases the reliability when determining
the readiness for covering, especially for screeds mixed with
aggregates (screed accelerators). With conventional cement
screeds, not all of the water that is required for processing the
screed is consumed by the setting/hydration process. Due to
excess water, the drying time is delayed and thus also the
readiness of the screed for covering.
This excess water is permanently bound in crystalline form by
screed accelerators, resulting in a significantly faster readiness
for covering. However, these aggregates may well result in
significant deviations in a CMmeasurement, making the
CRHmeasurement method an advantage.
The screed's readiness for covering is achieved once it can
permanently accommodate a floor covering without any
damages or defects caused.
To measure the relative humidity according to the CRH method,
only measuring devices suitable for this purpose should be used
which have been tested and approved for the CRH measuring
method by the Technical Commission on Construction
Adhesives(TKB).
