Carry out a CM measurement with a CM device or a CM measuring device. The laying of tiles and other materials on excessively damp subsoils can subsequently lead to considerable building defects and damage to the building. Therefore, you should take precautions in advance before taking any risks. Unfortunately, it is you who laid the floor, and who will be held accountable later. Therefore always better to play it safe. A CM measurement serves in the run-up to the installation of the clarification of whether a screed subfloor is already completely dry.
CM-Meter & CM Measurement – Precise Moisture Determination for Screed
The CM measurement (Calcium Carbide Method) is a proven method for determining residual moisture in screed, concrete, and other construction materials. It is essential for construction workers, tile setters, and floor layers to avoid damage caused by excessive moisture. A precise CM meter ensures reliable results and protects against costly complaints.
Why is CM Measurement Important?
When laying floor coverings such as tiles, parquet, or vinyl, the substrate must be sufficiently dry. Excess moisture can cause cracks, mold formation, and peeling. By using high-quality moisture meters, such issues can be detected and avoided early on.
Recommended Moisture & CM Meters
The
CM Moisture Meter Classic is the ideal tool for tile setters and construction workers. With the proven
Calcium Carbide Method, it allows for quick and precise moisture determination in screed.
- Precise results for screed and other materials
- Fast & efficient – measurement in a few minutes
- Easy handling – complete set with accessories
The
CM Digital Meter is an advancement of the Classic model and offers even greater accuracy. Thanks to the digital manometer, manual reading is no longer required, and the measurement result can be immediately printed as a protocol with the included printer.
- Digital display for highest accuracy
- Protocol printing for better traceability
- Complete equipment for quick measurements
Additional benefit: Includes a mobile printer for direct protocol printing.
The
Moisture Meter GM-200 is a versatile tool for determining the moisture content in floors and walls. It is ideal for construction projects to detect moisture early and prevent damage.
- 9 measurement scales for materials like screed, concrete, plaster, and wood
- Ergonomic design with non-slip grip
- Ready to use immediately – no recalibration required
How Does the CM Measurement Work?
- Sample Collection: A sample is taken from the screed, crushed, and weighed.
- Reaction with Calcium Carbide: The sample is placed in the meter along with a Calcium Carbide ampoule.
- Gas Development & Pressure Measurement: The chemical reaction produces acetylene gas, and the pressure is measured with a manometer.
- Reading the Result: The pressure value shows the moisture content of the screed.
Conclusion
With a CM meter or a moisture meter from Karl Dahm, you ensure that your screed is ready for installation and that costly damage is avoided. Whether analog or digital with protocol printing – choose the right device for your needs and work precisely, efficiently, and professionally!
