| 摘 要： | 选取DHT-2000型高精度温湿度测试仪、VaisalaHMP233温湿度仪和Syinyei S-1型露点仪三种典型的湿度标准设备,利用湿度检定箱对比分析了在30%-90%RH的湿度区间,三者测湿性能参数的差异。结果表明：DHT-2000型高精度温湿度测试仪与露点仪的测量精度相对较高,响应时间短,重复性较好。在取样湿度较高时,露点仪对环境要求较高,复现性相对较差。

| Abstract: | Three kinds of typical standard equipments,DHT-2000 high precision temperature and humidity tester,Vaisala HMP233 temperature and humidity instrument and Syinyei S-1 dewpoint hygrometer,are selected.By use of the humidity calibrating apparatus,the performance parameters of them are contrasted and analyzed in 30%-90% RH humidity range.The results show that DHT-2000 high precision temperature and humidity tester and dewpoint hygrometer have higher measurement acuracy,higher sensitivity and better repeatability.Since the measurement precision of dewpoint hygrometer depends on the environment temperature,its reproducibility is worse when the sampled humidity is higher. |
