Measurement of permeation resistance of constructive materials against under interest volatile toxic compounds has a huge importance not only from the point of user’s view but also from commercial one. It is necessary to distinguish an amount of permeated under interest toxic compound through protective material within both approaches. The PIEZOTEST device is designed for measurement of resistance of square constructive materials used for body surface protection. Commercially delivered device was not able to be calibrated. The aim of this information is to present calibration solution of this device with the help of a calibration extension, available device for dosage. The knowledge of concentration of toxic substances penetrating trough material is needed to calculate to gain information concerning protective properties. Therefore, it is necessary to calibrate a QCM sensor.
