Hydromat CM-B Standard

The Hydromat CM-B Standard is a device for determining the dampness of hardened building materials and various other materials using the calcium carbide method. The use of this measuring technique is recommended by various specialist associations for a range of measurement tasks and has thus been well known for years in practice alongside electrical measurement.

The Hydromat CM-B Standard is easy to use. All measurements can be made directly on the object using the tools contained in the carrying case and enable rapid information to be obtained concerning the current state of dampness.

The decision as to whether a floor or wall surface is ready for covering, for example, can be made immediately.

So the CM-B Standard is particularly suited for parquet reclining or floor tiling contractors, construction companies, architects, or surveyors.
