Concrete Moisture Meter For Measuring Moisture Content In Concrete Floors And Slabs



The Tramex Concrete Moisture Encounter 5, 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 Concrete Moisture Encounter 5, CME5, determines this instant and precise quantitative measurement of moisture content using Gravimetric testing as a baseline. This moisture meter for concrete tests the concrete to a depth of approximately 20mm (3⁄4″) into the slab.

The CME5 concrete moisture meter also provides readings for gypsum floor screeds as well as comparative readings making this moisture meter suitable to perform a concrete moisture test as per ASTM F2659.

The CME5 is a top quality moisture meter for concrete and an essential tool for non-destructive testing of concrete for professionals in the concrete coatings or flooring industry to help prevent moisture problems on concrete floors.

The use 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″ (100mm).

Moisture Mapping & Data Documentation

Concrete moisture test results can be visualized with the Tramex Meters App and turned into moisture maps, reports and charts for sharing. Bluetooth connectivity to mobile devices also helps to GeoTag test results, create, save and share photos.

Concrete Moisture Meter Features

Concrete Moisture Meter Design

The Tramex Concrete Moisture Encounter CME5 detects and evaluates the moisture conditions within the slab or screed by non-destructively measuring the 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 in the material. The Tramex CME5 concrete moisture meter determines the strength of the current and 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.

Concrete Moisture Meter – Operating procedure

To carry out tests simply brush any dust from a smooth area of concrete and also from the electrodes, switch on the CME5 concrete moisture meter and place it firmly onto the surface, fully compressing the spring-loaded, signal-enhancing contacts on the base. Read the moisture content from the clear analogue dial. The Tramex Concrete Moisture Encounter CME5 is calibrated to give percentage moisture content readings on clean, bare dust free concrete floor slabs, with a depth of penetration of approx. ¾” (20 mm). Readings taken on concrete slabs through paint, coatings, adhesives or other materials on the surface should be regarded as qualitative or comparative and not quantitative.
