中文摘要：

为评价云南天文台丽江2．4m望远镜的圆顶视宁度．研制了一种能测量温度、气压和微温脉动的仪器。在天文圆顶附近，望远镜前方光路上，放置几组微温传感器，可以测得圆顶附近影响天文观测的湍流强度的分布情况。介绍了这套仪器的基本原理，电路设计，程序设计，实验定标以及一个简单的测试。

英文摘要：

For evaluating the dome seeing of the 2.4m telescope at Lijiang of the Yunnan Observatory, an instrument is designed to measure temperature, air pressure, and atmospheric temperature fluctuations in an astronomical dome. The distribution of turbulence intensity in the dome affecting seeing can be obtained from the temperature data collected by some sensors set in the light path of the telescope. The basic principle and circuit/software design are described in this paper. In addition, the calibration and on-site test results are presented.
