In order to evaluate the accuracy of the original data of VOCs online monitoring equipments, an evaluation method for data recognition capability of VOCs online monitoring equipments was established. The results showed that there were some differences in the performance of the eight VOCs online monitoring equipments in data recognition capability, and the average relative deviation between original data and manual audit data ranged from ?100% to 56 652%. Compared with high-carbon species, a greater mean relative deviation between the original data and the manual audit data occurred for low-carbon species. According to the application case analysis, the data recognition index (DRI) proposed in this study could quantitatively distinguish the data recognition capability of different VOCs online monitoring equipments. This method not only provided a new assessment index for the evaluation of VOCs online monitoring equipments in the future, but also could make a scientific evaluation for the rapid analysis and application capability of other online monitoring equipments.
