Calibration Advice

When doing a moisture survey with the Tramex CMEX5 it's good practice to regularly check the calibration of the meter before commencing an inspection. 

This can be carried out with a Tramex Calibration Checkplate. In combination with the Tramex Meters App, the calibration test results can be geo tagged, helping avoid questioning the validity of the calibration of your Tramex Meter. 

Should it be found that readings are outside the set tolerances, it is recommended that the Concrete Moisture Encounter CMEX5 be returned for re-calibration, click here for more information.

Please note that calibration adjustments should not be carried out by anyone other than Tramex or their authorised service provider who will issue a calibration certificate on completion.
