空气中化学污染物计量（MAC Poll）是EURAMET欧洲计量研究计划的一个联合研究项目，在其他活动中涉及用于空气质量监测的低成本气体传感器。气体传感器被认为是空气质量指令中规定的“指示性测量”的新兴测量设备。与参考测量相比，气体传感器可以以更低的成本监测空气污染。该指令允许在未超过上限评估阈值（UAT）的区域不受限制地使用指示性测量，同时允许在超过上限评估阈值的区域将最低参考测量值减少50%。该指令没有指定任何指示性方法，但它要求证明它们可以满足数据质量目标（DQO），该目标的严格程度约为参考方法的两倍。DQO被定义为一个相对扩展的不确定性。由于该指令没有为该演示提供任何指导，MACPoll内部已决定起草一份评估气体传感器的协议。
Metrology for Chemical Pollutants in Air (MAC Poll) is a joint research project of the European Metrology Research Programme of EURAMET that among other activities deals with lowcost gas sensors for air quality monitoring. Gas sensors are identified as emerging measuring devices for “indicative measu rements” regulated in the Air Quality Directive. Compared to reference measurements, gas sensors would allow air pollution monitoring at a lower cost. The Directive allows using indicative measurements without restriction in the zones where the upper asses sment threshold (UAT) is not exceeded while they permit a reduction of 50 % of the minimum reference measurements where the UAT is exceeded. The Directive does not specify any indicative method but it requires to demonstrate that they can meet a data quali ty objective (DQO) that is about twice less stringent than the one of reference methods. The DQO is defined as a relative expanded uncertainty. Since the Directive does not give any guidance for this demonstration, within MACPoll it has been decided to draft a protocol for the evaluation of gas sensors.
