The Concrete Moisture Encounter CME5 from Tramex is a non-destructive moisture meter for concrete floors and screeds: immediate readings in accordance with the ASTM F2659 standard, with scales equivalent to the carbide method (CM) for concrete and anhydrite.
- Non-destructive measurement: moisture in concrete and screeds
- ASTM F2659 standard: immediate, repeatable readings
- CM scale for concrete: carbide equivalent 0–4
- CM scale for anhydrite: equivalent 0–1.9
- Moisture content: range 0–6% MC
- Penetration depth: approx. 20 mm (¾”)
- Bluetooth + App: Tramex Meters; optional extension handle
The CME5 works on the principle of impedance measurement: the coplanar electrodes on the base, pressed against the surface by a spring load, transmit a low-frequency signal into the concrete. The change in impedance caused by the moisture is converted and shown on a clear analogue dial.
It is calibrated to give the percentage moisture content on clean, uncovered concrete slabs. Readings taken through paint, coverings or adhesives are to be regarded as qualitative or comparative. It allows quick, repeatable testing over large areas.
