摘要
遵循道尔顿定律建立的双压力法恒湿气体发生器,各项技术指标高于湿度计量一等标准要求,可用于校准和测量湿度仪器及测湿元件;遵循理想气体状态方程及静态容积法配制乙醇标准气体,建立的呼出气体酒精含量探测器检定装置,其不确定度优于被检探测器允许相对误差的三倍以上,可以满足呼出气体酒精含量探测器检定的需要。
The specifitions of a double—pressure,Constanthumidity Gas Generator based on Dalton law are superior to the standard of first—class humidity measurement requirements. It can be used to calibrate and measure bumidometets or elements used for measuring humidity. Alcohol standard gas made according to ideal gas state equation and static volume method can be used to calibrte the alcohol content detector of exhalation gas. Its uncertainty of measurement is less than one third of permissibly relative error of the verified detector. Thus,it satisfies the needs of instrument verification.
