单点校准在环境空气自动监测系统中的应用探讨

Approach on Application of Single PointCalibration to Environmental Air AutomaticMonitoring System

单点校准法是环境空气自动监测系统中最常规的例行检查。在实际应用中,通过分析校准响应值的零点漂移和跨度漂移变化,判断监测仪器的运行状态及环境条件的变化,从而保证监测数据的准确性和可靠性。

The single point calibration is the most regular check-up in environmental air automatic monitoring system. In practice, it is used to judge the operation status of the monitoring apparatus and the variation of environmental condition by excursion of zero calibration and span calibration of SO2, and to ensure the veracity and reliability of monitoring data.
