Hand-held weld checker DRM-4012 手持式焊接檢查drm-4012

Description
描述
The AL-40 welded electrical connections tester is designed for precise and easy quality control of welded electrical connections. The instrument is used to measure electrical resistance formed by the fusion of the weld with the conductors. The accurate and competitive instrument is specially designed to test electrical connections/exothermic welds (Cadweld?) with 0,01μ resolution.
al-40焊接的電氣連接測試儀是用于焊接的電氣連接精密，質量容易控制。該儀器是用來測量由焊接與導線的熔化形成的電阻。準確的和有競爭力的儀器是專門設計用來測試電氣連接/放熱焊接（CADWELD放熱?）和0.01μ分辨率。
A good exothermic weld provides electrical resistance of about ten micro ohms, and the difference between a good and a bad weld can be as low as one micro ohm. The accuracy and resolution of a tool plays an important role to measure this difference. The joints are welded in the field to provide portable and ease to use tool. AL-40 represents a unique tool in this category.
一個好的放熱焊接提供約十微歐姆電阻，和一個好的和壞的焊縫之間的差異可以作為一個微歐姆低。一種工具的精度和分辨率對衡量這種差異起著重要的作用。接頭在現場焊接，以提供便攜式和易于使用的工具。al-40代表一個獨特的工具，這類。
