Description Lakeshore425高斯计简介
美国Lakeshore公司生产的高斯计/特斯拉计是美国的一种工业标准，在世界范围内有广泛的客户，Lakeshore高斯计主要型号有：410型高斯计/特斯拉计是一种手持式高斯计，它以轻巧方便、测量精确和多种功能深受用户青睐；421型高斯计/特斯拉计是LakeShore为适应永磁工业的动态变化而设计的；Lakeshore425型高斯计/特斯拉计是LakeShore为适应永磁工业的动态变化而设计的，逐渐替代421型高斯计；455型高斯计/特斯拉计号是一款采用先进数字信号处理技术，价格适中的台式高斯计；460型三通道霍尔效应高斯计可以同时进行三轴测量并计算磁场或者3个单轴同时测量； 475高斯计/特斯拉计除了具有455高斯计所有的功能之外，还增加了峰值捕捉、温度显示、频率显示、报警延迟、磁场控制等功能。各种不同型号可以测量直流磁场，交流磁场，脉冲磁场，低频交流磁场等。它们带有的探头都可以互换。
Designed to meet the demanding needs of the permanent magnet industry, the Lake Shore Model 425 gaussmeter provides high end functionality and performance in an affordable desktop instrument. Magnet testing and sorting have never been easier. When used in combination with the built in relay and audible alarm features, the Model 425 takes the guesswork out of pass/fail criteria. Additional features including DC to 10 kHz AC frequency response, max hold and relative measurement make the Model 425 the ideal tool for your manufacturing, quality control and R&D flux density measurement applications. For added functionality and value, the Model 425 also includes a standard Lake Shore Hall probe. Put the Model 425 gaussmeter to use with confidence knowing it’s supported by the industry leading experts in magnet measurement instrument, sensor and Hall probe technology.
