摘要
气体检测报警器的检测结果需要进行检定,在测量过程如所使用的设备发生变化时,需要重新审查不确定度评估结果,笔者通过对HL-200型系列气体检测报警仪分别通入量程的20%、50%、80%附近的3个浓度点进行检测,对气体检测报警器示值误差测量结果分析及不确定度评定进行了探讨,结果表明示值误差符合检定要求,不确定度评定结果符合测量要求。
Gas detection alarm testing results need verification for the measurement process.If the equipment used for Gas detection alarm testing changes,we should review uncertainty assessment results.Using the HL-200 type series gas detection alarming device,this article gives gas detection detection and measurement respectively in near 20%, 50 %,8 0% of three concentration point.Error alarm is analyzed and the uncertainty is discussed,and the results show that the over-error of indication accords with verification requirements,the error of the uncertainty results accord with measurement requirements.
