The Tramex Concrete Moisture Encounter CME5, the updated CME4 Concrete Moisture Encounter, is a non-destructive analog concrete moisture meter for measuring quantitative moisture content in concrete floors and slabs. The CME5 delivers instant and precise quantitative measurement of moisture content using gravimetric testing as a baseline, testing the concrete to a depth of approximately 3/4 inch (20mm) into the slab.

The CME5 also provides readings for gypsum floor screeds as well as comparative readings, making it suitable for performing a concrete moisture test as per ASTM F2659. It is an essential tool for non-destructive testing of concrete for professionals in the concrete coatings and flooring industries, helping to prevent moisture problems on concrete floors.

The capability of the CME5 can be extended with the optional Concrete Moisture Probe, which detects in-situ quantitative moisture content within the concrete down to an extendable depth of up to 4 inches (100mm). The CME5 is also included in several Tramex concrete moisture test kits.

Concrete moisture test results can be visualised with the Tramex Meters App and turned into moisture maps, reports and charts for sharing. Bluetooth connectivity to mobile devices also allows GeoTagging of test results and the creation and sharing of photos. The CME5 is the new and improved version of the well-established and trusted Concrete Moisture Encounter CME4.

Features

• Non-destructive in operation, with no need to probe, drill or mechanically damage the surface
• Clear, easy to read analog dial
• Instant and precise readings to a depth of approximately 3/4 inch into the slab
• Bluetooth connection to the accompanying iOS and Android app for reporting and moisture mapping
• Hold function freezes the meter reading when inspecting areas where the meter face is not visible, and for easy recording of data
• Reproducible and reliable results
• Spring-loaded contact pins compensate for uneven concrete and boost signal penetration
• Rugged, ergonomically designed enclosure

How It Works

The CME5 detects and evaluates moisture conditions within the slab or screed by non-destructively measuring electrical impedance. A low frequency electronic signal is transmitted into the material under test via the electrodes in the base of the instrument. The strength of this signal varies in proportion to the amount of moisture present. The CME5 converts this to a moisture content value for concrete slabs and a comparative value for other cementitious floor screeds, displayed on a large clear analog dial.

Operating procedure: brush any dust from a smooth area of concrete and from the electrodes, switch on the meter and place it firmly onto the surface, fully compressing the spring-loaded signal-enhancing contacts on the base, then read the moisture content from the dial. The CME5 is calibrated to give percentage moisture content readings on clean, bare, dust free concrete floor slabs with a depth of penetration of approximately 3/4 inch (20mm). Readings taken through paint, coatings, adhesives or other surface materials should be regarded as qualitative or comparative rather than quantitative.
