摘要
手持式激光甲烷探测器是近年来新兴的一种甲烷检测仪器,具有便于携带、灵敏度高、响应时间短、监测区域灵活广阔等优点,但目前尚无相关的计量技术规程规范及相应的计量标准器对其进行有效溯源.本文从理论上设计了一套用于该仪器的量值溯源装置,并进行不确定度的评定,为相关技术文件的编写和计量标准的建立提供理论依据和技术支撑.
Abstract
The handheld laser methane detector is a kind of methane detection instrument emerging in recent years,which has the advantages of easy to carry,high sensitivity,short response time,flexible and broad monitoring area,etc.,but there are no relevant metrology technical specifications and corresponding metrology standards to trace its effective source.In this paper,a set of measurement traceability device for the instrument is designed theoretically,and the uncertainty is evaluated,which provides theoretical basis and technical support for the preparation of rele-vant technical documents and the establishment of measurement standards.
