SZ-1数字指示管是上海电子管厂1965年的新产品之一,它是一种冷阴极辉光放电管,主要用于数字化测量仪器及计算测量仪器.这种管子的优点是:(1)计数精确、迅速,计数频率可达2×10~6次/秒;(2)亮度高,可在距离10米处清楚读数;(3)可以给出清晰而直观的数字指示;(4)相对于仪表指示,其占有的体积小,寿命长;(5)由于是冷阴极辉光放电管,其消耗的功率小;(6)显示美观,阅读方便.
SZ-1 digital indicator tube is one of the new products of Shanghai Electronic Tube Plant in 1965. It is a kind of cold cathode glow discharge tube, mainly used in digital measuring instrument and calculation measuring instrument. The advantages of this tube are: (1) Counting is accurate and fast, counting frequency can reach 2 × 10 ~ 6 times / second; (2) High brightness, can be clearly read at a distance of 10 meters; (3) Clear and intuitive digital indication can be given; (4) Relative In the instrument indicates that its small size, long life; (5) Because it is cold cathode glow discharge tube, which consumes less power; (6) Display beautiful, easy to read.
