The gases style exceeding the element which is heated electrically with flux, flow making pass, the aerosol which floats in process and the gases style which measure the 1st cooling effect exceeding the element which is heated electrically with flux, flow making pass, in order the process which measures the 2nd cooling effect, and, it measures the difference of the 1st cooling effect and the 2nd cooling effect, includes the process which correlates this difference with aerosol density, to measure the sterilization medicine dosage, the gases style () in, density of the sterilization medicine aerosol such as flow of the air for example such as water hydrogen peroxideThe method of measuring is offered. Therefore, it is possible to measure the entire dosage. The dosage where the sterilization medicine aerosol is measured is forwarded and by the feedback loop the quantity of the aerosol which when is forwarded reaches to the specified dosage, it is possible for further forwarding of the sterilization medicine aerosol to be stopped. This method makes the guarantee of sterilization possible.ガス流を流速で電気的に加熱された素子を越えて流過させて第1の冷却効果を計測する工程、ガス流中に浮遊するエアロゾルを流速で電気的に加熱された素子を越えて流過させて第2の冷却効果を計測する工程、および、第1の冷却効果と第2の冷却効果との差を計測し、この差をエアロゾル密度と相関させる工程を含む、滅菌剤適用量を計測するために、ガス流(空気の流れなど)中の、例えば水性過酸化水素といった滅菌剤エアロゾルの密度を計測する方法を提供する。それ故、総適用量を測定することが可能である。滅菌剤エアロゾルの計測された適用量は、フィードバックループにより送出され、送出されたエアロゾルの量が所定の適用量に達したら、滅菌剤エアロゾルのさらなる送出が停止されることが可能である。この方法は、滅菌の保証を可能とする。
