Accessory for the Tramex CME5 and CMEX5 measuring instruments .
It allows for the measurement of the moisture content (%) in concrete and anhydrite layers at depths of up to
100 mm. It operates by measuring the electrical impedance in the material, which changes as
the moisture content of the medium changes. The device measures the amplitude of the current flowing between the embedded
transmitter electrode and the pins of the receiver electrode, and uses this to determine the % moisture content
in the layer.
To perform the measurement, drill a 19-mm-diameter hole to a depth of 40% of the thickness
of the layer being tested (if it dries from only one side—such as a floor) or 20% (if it dries from both
sides—such as a wall). After drilling, clean the hole by vacuuming it. Adjust the length of the electrode
to match the depth of the hole, press the probe against the surface being tested using the CME or CMEX measuring device
, and take a reading.
Measurement range:
- Moisture content in concrete with Tramex CMEX5: 0–6.9%
- Moisture content in concrete measured with the Tramex CME5: 0–6%
- Penetration depth: probe depth of 3 cm (1 1/4”) for concrete with a thickness of 5 to 10 cm (2”–4”)
- Probe depth: 5.7 cm (2 1/4”) for concrete with a depth of 10 to 15 cm (4” to 6”)
- Probe depth: 8.3 cm (3 1/4”) for concrete slabs 15 to 22 cm (6”–9”) thick
- Probe depth: 10.8 cm (4 1/4”) for concrete slabs 22 to 28 cm (9”–11”) thick
