摘　　要：采用30m^3实验舱,在温度为(20±2)℃,对不同湿度条件下仪器现场检测的情况进行了探讨。当环境湿度在一定范围内仪器法的检测结果能符合技术要求。当湿度超过75%RH时,检测结果在某些测试浓度段出现较大偏差。当湿度超过80%RH时,检测结果已不符合技术要求。湿度对室内空气质量采用仪器法现场检测的结果有显著影响。Conducted experiments by testing the Formaldehyde Portable Detectors in an experimental room with 30m3 in space, with different levels of humidity at temperatures of （20±2）℃. Within a certain range of environment humidity, the testing results of Formaldehyde Portable Detectors met technical standards quite well. With humidity of over 75%RH, testing results deviated from the accurate value considerably. When the humidity is above 80%RH, the readings of the Formaldehyde Portable Detectors cannot fulfill technical standards. Humidity has significant impact on the accuracy of Formaldehyde Portable Detectors.
