Abstract

?detecção de oscilações na quantidade de gás de teste durante busca de vazamento por aspiração?, por tratar-se a presente invenção de um método para detecção de oscilações na quantidade de gás de teste detectada por uma sonda aspiradora (20) de um detector de vazamento (18) no fluxo de gás da atmosfera em torno de uma peça de teste (12) pressurizada com um gás de teste livre de oxigênio contendo pelo menos uma quantidade de dióxido de carbono (co2), caracterizado pelo fato de a quantidade de oxigênio no ar ambiental ser medida.
