KRL CMEX 5 Measurement Set – Modern Moisture Measurement for Maximum Safety in Screed Testing
The KRL CMEX 5 Measurement Set enables particularly safe and modern evaluation of the readiness for covering of screeds according to DIN EN 17668:2022. Especially with modern screeds containing additives, accelerators or innovative binders such as CEM II cement, the traditional CM method often reaches its limits. This innovative measuring system helps craftsmen and flooring installers precisely determine the actual moisture condition of a screed.
Unlike conventional CM measurement, the KRL method not only evaluates the absolute residual moisture content of the sample material, but also the actual moisture condition of the screed. The corresponding relative humidity of an extracted screed sample is measured. This allows a much safer assessment of readiness for covering and significantly reduces the risk of later moisture damage or complaints.
The modern KRL CMEX 5 Measurement Set is ideally suited for construction site conditions and can be used directly by craftsmen on site.

KRL Measurement for Modern Screeds and Reliable Readiness for Covering
The innovative KRL measurement has established itself as the current state of the art and is normatively defined in DIN EN 17668. The method enables material-independent determination of the moisture condition of screeds and is suitable for classic cement screeds as well as modern mixed forms or calcium sulphate screeds.
Especially with screeds containing additives or accelerated drying systems, the combination of CM and KRL measurement provides significantly more safety. Both measurements can be carried out in parallel at the same sampling point. This saves time and provides a particularly reliable assessment of readiness for covering.
Modern Moisture Meter with Digital Documentation
The integrated moisture meter CMEX 5 impresses with modern measuring technology and extensive additional functions. The permanently integrated climate sensor in the KRL cup enables direct measurement without external sensors. In addition, the app function supports convenient digital documentation of the measurement results.
The powerful moisture meter also offers all known additional CMEX5 functions for non-destructive moisture measurement. This makes the system ideal for professional users in flooring, tiling and screed applications.
Alternative to CM Meters with Extended Capabilities
Today, the KRL system is considered a modern alternative to CM meters, especially for demanding screed constructions and modern building materials. While classic CM measurements only determine residual moisture content, the KRL method additionally enables evaluation of the actual moisture condition of the screed.
This provides users with a much more precise assessment of how much moisture is still being released into the surrounding air during the drying process. Especially with sensitive floor coverings and modern screed systems, this method offers a high level of safety.
Many specialist companies therefore now use the KRL method as a supplementary alternative to CM meters in order to avoid long-term moisture damage.
Easy KRL Measurement on the Construction Site
The KRL measurement is carried out similarly to the traditional CM method. A representative screed sample is taken from the entire screed cross-section and then filled into the KRL cup. After sealing the measuring chamber, the measuring probe is inserted and the measurement started.
After approximately 15 to 30 minutes, the measured value stabilizes and provides a meaningful evaluation of the moisture condition. The system is ideal for professional construction site use and enables fast, precise and standards-compliant measurement results.
FAQ about the KRL Measuring Set CMEX 5
What is the KRL Measuring Set CMEX 5?
The KRL Measuring Set CMEX 5 is a modern measuring system for the reliable assessment of screed readiness for covering.
It combines the KRL method with modern digital measuring technology and is ideal for professional construction site applications. Especially with modern screeds containing additives or accelerated drying systems, the system provides a significantly more precise assessment of the actual moisture condition. This considerably reduces the risk of moisture damage and later complaints. At the same time, the measuring system supports standard-compliant and reliable measurement results directly on site.
How does the KRL measurement work?
During KRL measurement, the corresponding relative humidity of a screed sample is measured.
This allows the actual moisture condition of the screed to be determined much more precisely than with pure residual moisture measurement. The sample is placed into the special KRL cup and measured using the integrated climate probe. After a short time, the measured value stabilizes and provides a reliable assessment of readiness for covering. Especially with modern screed systems, the method offers a high level of measurement reliability.
What advantages does the CMEX 5 moisture meter offer?
The moisture meter features an integrated climate sensor, digital documentation functions via app and extensive additional functions for non-destructive moisture measurement.
This allows measurement results to be recorded and documented conveniently. At the same time, the device enables fast and precise measurements directly on the construction site. The integrated sensor also reduces effort, as no external measuring probes are required. Professional users particularly benefit from the modern measuring technology and easy handling.
Is the system an alternative to CM measuring devices?
Yes, the system is considered a modern alternative to CM measuring devices, as it evaluates not only the residual moisture content but also the actual moisture condition of the screed.
This provides users with a much more accurate assessment of readiness for covering. Especially with sensitive floor coverings or modern screeds containing additives, the KRL method offers additional safety. Many specialist companies therefore use KRL measurement as a supplement or alternative to the classic CM method. This helps avoid long-term moisture problems and improves the quality of screed testing.
Which screeds is the KRL measuring device suitable for?
The KRL measuring device is suitable for cement screeds, calcium sulphate screeds, modern mixed screeds and screeds with additives or accelerators.
Thanks to the material-independent measuring method, the actual moisture condition can be determined very precisely. Especially with modern screed systems featuring modified drying properties, the KRL method offers a high level of reliability. The system is suitable for both classic construction site applications and demanding renovation or new construction projects. This provides floor layers, tile setters and screed installers with reliable measurement results.
