以下是ZDR-F20温湿度记录仪的产品中英文介绍：

ZDR-F20温湿度记录仪是一款功能强大的环境监测设备。它能够全程跟踪记录温湿度数据，记录时间长，若以15分钟记录一次数据为例，可记录长达5个月甚至更长时间。该设备采用锂电池和外接电源双重供电系统，整机功耗小，在有交流电的情况下可自动切换为外接电源供电，电池使用寿命可达2年以上。

其测量范围广泛，温度测量范围为-40℃～100℃，湿度测量范围为0～100%RH。测量精度较高，温度精度在-20℃～60℃内为±0.5℃，其外为±1℃，湿度精度为±3%RH。记录间隔可从2秒至24小时任意设置，能够满足不同场景下的监测需求。

此外，ZDR-F20温湿度记录仪配备大屏显示，操作简单，性能可靠，即使在恶劣环境下也能正常工作，且失电时数据不会丢失。用户还可以自行设定温度的上下限，一旦超限，报警器会自动报警。其软件有中英文两种版本可供选择，英文版具有国际通用性，软件功能强大，可显示整个过程的最大值、最小值及平均值，数据查看方便。下载的数据可以做成WORD或EXCEL文档，便于研究或上级单位的检查。

The ZDR-F20 temperature and humidity recorder is a powerful environmental monitoring device. It can track and record temperature and humidity data throughout the entire process, with a long recording duration. For example, if data is recorded every 15 minutes, it can last for up to 5 months or even longer. The device uses a dual power supply system of lithium batteries and external power sources, with low power consumption. It can automatically switch to external power supply when there is AC power, and the battery life can last for more than 2 years.

It has a wide measurement range, with temperature ranging from -40℃ to 100℃ and humidity ranging from 0 to 100% RH. The measurement accuracy is relatively high, with temperature accuracy of ±0.5℃ within -20℃ to 60℃ and ±1℃ outside this range, and humidity accuracy of ±3% RH. The recording interval can be set arbitrarily from 2 seconds to 24 hours, meeting the monitoring needs of different scenarios.

In addition, the ZDR-F20 temperature and humidity recorder is equipped with a large screen display, simple operation, and reliable performance. It can still work normally in harsh environments, and data will not be lost in case of power failure. Users can set the upper and lower limits of temperature by themselves, and the alarm will be triggered automatically once the limit is exceeded. The software of the device is available in both Chinese and English versions, with the English version being internationally universal. The software is powerful, capable of displaying the maximum, minimum, and average values of the entire process, making data viewing convenient. The downloaded data can be made into WORD or EXCEL documents for research or inspection by higher authorities.
