CM material moisture measuring devices
For a quick and reliable moisture determination in building materials
CM measurements provide protection against expensive complaints later on.
Professionals already know: Structural damages are often attributable to excessive residual moisture in the ground.
With Trotec's CM Complete sets you can carry out your measurements quickly and reliably. This way, the residual moisture content in processed construction materials such as floor beddings etc. can be precisely determined directly on site and without the need for additional aids or tools and documented with the supplied log printer (CM Set Business).
Multiple print-outs simplify the administration and in case of a dispute provide proof that the mandatory testing requirements have been met.
Thanks to the accurate measuring technology, you can do without time-consuming laboratory tests.
The value displayed on the pressure gauge corresponds to the actual residual moisture in per cent – no laborious conversion required.
Surface thermometer to avoid measurement errors ...
The conversion tables of all CM devices that are usually available on the market are based on a constant ambient temperature of 20 °C. In the best case, this temperature is present at the beginning and also at the end of a measurement.
If this reference temperature is deviated at the beginning or end of a measurement and not observed, this will result in a more or less relevant error depending on the degree of deviation:
For every 3 °C deviation, the error is 1 % of the pressure (the temperature is the same at the beginning and end of the measurement).
For this reason, all Trotec CM devices are equipped with a surface thermometer which indicates the cylinder temperature. This way, any temperature errors can be detected.
If, for example, a measurement was performed at a constant temperature of 35 °C and a pressure of 0.8 bar was indicated, the CM % moisture content for a sample of 50 g according to the table or scale is 1.57 CM %.
The same measurement carried out at a constant temperature of 20 °C would have resulted in a pressure of 0.76 bar (5 % less) and thus in a moisture value of 1.49 CM %.
The Trotec CM complete sets convince with their easy operability and high precision:

CM log printer
For the documentation of your CM measured data directly on site
Comes fully equipped with protective cover, charger and spare roll of paper. Prints the measuring result directly as log. It is possible to create several print-outs with log numbers during one measurement only.
The log comprises:
- Adjustable log heading for company data and information on the measuring point
- Selection list for the measured test material
- Pressure curve during measurement
- Overall measurement duration in minutes and seconds
- Automatic calculation of the CM % moisture for 10, 20, 50 and 100 g weighed portions
- Adjustable log footer for documentation, location, user and building owner
The CM log printer is the ideal supplementation for the CM set Business...
Hint: combined moisture measurement
Increased safety based on combined check of the readiness for covering
CM measuring is a generally accepted test method for the evaluation of the readiness for covering of screeds. As with all methods of measurement, however, the use of only one procedure can always lead to misinterpretation.
Recently craftsmen and building owners have had to deal in court with the problem that in individual cases CM measurement results indicated the readiness for covering, even though the screed just wasn't ready!
Therefore, play it safe and combine the floor moisture content measurement method approved in continental Europe (CM measurement) with the equilibrium moisture content measurement which has become established as standard method for many a year in e.g. Northern Europe.
In case of the combined moisture measurement, first the equilibrium moisture content and then the moisture content of the sample is determined by use of the very same sample.
The combined moisture measurement method affords users of CM measuring devices more security when assessing the readiness for covering of screeds without causing significant additional expenses. Moreover, the familiar CM measuring device can be used for this additional measurement.
The determination of both values – equilibrium moisture content and moisture content of the sample – allows for a more reliable assessment of the readiness for covering than just one of the two measurement methods.
Since both measuring results have been determined using the same sample, combined moisture measurement results in yet more security for the floor layer!
Required equipment for combined moisture measurement: Other than the already available CM device, only the CM hygro combination cap and a T210 thermohygrometer are required, or, if a T3000 measuring device is available, a TS 210 SDI climate sensor is needed.
A few practical benefits:
- Robust design in metal carrying case
- For weighed portions of 100 g (calcium sulphate flow screed)
- Attractive value-for-money ratio
- Direct indication of CM moisture with an accuracy class to 0.1 % (Business)
- Log printer documentation protects against damages and follow-up costs (Business)
- Complete sets with 2 precision pressure gauges – optionally either mechanical or digital
