摘　　要：对10批次便携式半导体气敏传感器法甲醛检测仪和10批次电化学传感器法甲醛检测仪的示值误差进行比较。用30 m^(3)环境舱静态模拟三种不同甲醛浓度的室内环境。结果表明,在设定的环境中,便携式半导体气敏传感器法甲醛检测仪与酚试剂分光光度法检测结果的示值误差大于15%,不适用于室内环境中甲醛浓度的准确检测;而电化学传感器法甲醛检测仪与酚试剂分光光度法检测结果的示值误差均小于15%,适用于室内环境甲醛浓度的准确检测。The indication errors of 10 batches of household portable semiconductor gas detector and 10 batches of electrochemical sensor formaldehyde detectors were compared.Different formaldehyde concentrations of three indoor environments were simulated a 30 m^(3) environmental chamber.The results show that the error between the home portable semiconductor gas detector formaldehyde detector and MBTH spectrophotometer is more than 15%,which was not suitable for the accurate detection of formaldehyde concentration in the indoor environment.The error between electrochemical sensor formaldehyde detector and MBTH spectrophotometer is less than 15%,which was suitable for the accurate detection of formaldehyde concentration in the indoor environment.
