How to perform the Tramex Complete Concrete Moisture Test System

Step 1: Check Ambient conditions

When arriving on site, take note of the ambient temperature, ambient relative humidity and dew point conditions. These readings will be needed for reference in later steps.

Ensure that the test area is in ‘in service’ conditions, which means that the temperature should be between 65-85℉ or 18-30℃, and relative humidity readings between 40-60 %RH. 

As concrete is generally 1-2 degrees cooler than the air temperature, be aware of any potential condensation in the top layer of the slab, which may be caused by moisture moving from hot to cold.

These tests can be performed using either the Concrete Moisture Encounter X5 - CMEX5 with built-in hygrometer or with the IRT2DP.

Step 3: Take a non-destructive impedance concrete moisture readings

Perform a non-destructive impedance test using either a Tramex Concrete Moisture Encounter CME5 or CMEX5. 

These moisture meters provide an instant, quantitative moisture content reading up to ¾ inch (20mm) into the concrete floor or slab without any need to drill or damage it.

Step 5: Performing the ASTM F2170 Relative Humidity test

After taking the Concrete Moisture Probe readings, fit the drilled holes with hole liners in preparation for performing the relative humidity test.

When performing a Relative Humidity test in a concrete slab it is essential to follow the international industry guidelines such as ASTM F2170, BS8201 and BS8203. These guidelines provide specific instructions on how to perform the test to obtain reliable reading results. 

The Tramex Hygro-i2® relative humidity probes are the most advanced, resilient and reusable RH probe on the market today. 

The Tramex system enables future testing by removing the probe and sealing the sleeve for later use, thus providing a more reliable and accurate test. 

Always check your flooring manufacturers' recommendations and ensure that your readings are within the specified parameters.
