An original method, based on the continuous circulation in a closed circuit of saturated HTO vapour, is presented. The saturated vapour are obtained by bubbling from vials containing different tritium standard solutions (IFIN-HH-TDCR method). The main difference from the usual method, elaborated by Osborne, is the use of saturated vapour, which eliminates the measurement in liquid scintillator of the recovered non-saturated vapour. Tritium Monitors type MT-1 made in IFIN-HH were calibrated. The measurements were carried out for three levels of the activity concentration: 0.0180, 0.701 and 1.73 MBq.g{sup -1}. The mean response was R=2.25.10{sup -13} A/(MBq m{sup -3}) with a relative combined uncertainty lower than 4%. The value agrees with the result obtained with the Osborne method, R{sub Os}=2.30.10{sup -13}A/(MBq m{sup -3}) and with the estimated theoretical value, 2.29 10{sup -13}A/(MBq m{sup -3})
