Tramex™ CMEXpert II

Complete Moisture and Humidity Meter for Flooring

For evaluating the moisture conditions of concrete and other slabs and screeds per ASTM F2659 (Nondestructive method) and relative humidity measurement to ASTM F2170 (In situ method) and British Standard 8201, 8203 (Hood Method) with optional Hygro-i2® probe

Instant and non-destructive moisture content tests per ASTM F2659 with the CMEX II, a digital version of the CME4 handheld electronic moisture meter, designed for the instant and precise measurement of moisture content in concrete slabs and giving comparative readings in other cementitious floor screeds.

Incorporating plug-in ports for the optional Hygro-i2® relative humidity probe and heavy-duty pin-type wood probes, this meter transforms into the ideal all-in-one instrument for the flooring professional.

Product Design

top
The CMEX II 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 CMEX II 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 digital dial.

 

Probe Modes

top

Hygrometer Mode - When the optional Tramex Hygro-i2® relative humidity probe is plugged into the CMEX II, the instrument automatically changes to Hygrometer Mode, allowing for in situ relative humidity (RH) testing of floor slabs per ASTM F2170 and BS 8201, 8203 Hood Method, as well as ambient conditions of temperature, relative humidity, dew point and mixing ratios. This resilient probe is reusable and can be checked regularly for calibration.

Wood Pin-Type Probe Mode - In Pin-probe mode by plugging in the optional handheld or hammer probe the CMEX II becomes a resistance type pin meter for determining the moisture content of wood and wood based products. The CMEX II gives moisture content readings from 7% to 40% in wood. A species adjustment table and a temperature adjustment chart are supplied for precise readings in woods of varying densities and readings taken in various temperatures.

Concrete Encounter CME4

Non-Destructive Moisture Detector

ASTM F2659

Instant and non-destructive tests per ASTM F2659 with the Tramex CME4, a non-invasive handheld electronic instrument used for testing moisture conditions in concrete slabs and giving comparative readings in other cementitious floor screeds.

Precise and easy to use, the CME4 allows the user to make multiple tests over a large area in the shortest possible time.

Screeds and concrete floors must be dry before a floor covering is installed. Don’t take risks with excess moisture! Moisture test before you install a floor covering.

How It Works

top

Product Design - CME4 Concrete Encounter 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 CME4 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.

Operating Procedure - To carry out tests simply brush any dust from a smooth area of concrete and also from the electrodes, switch on the Concrete Encounter CME4 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 analog dial. The CME4 is calibrated to give percentage moisture content readings on clean, bare dust free concrete floor slabs, with a depth of penetration of approx. 3/4". 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.
