这种金属材料鉴别器,通过测头与被检测材料的接触,很容易鉴别材质,是一种轻便的手提式材料鉴别装置(国内通常采用钢材化验来检定钢材材质—译者)。一、特点1、利用钢材材质热电动势,在短时间内就可以得出检测结果; 2、鉴定各种不同金属材料非常方便; 3、操作简单,不需要熟练的技术; 4、对被检测材料无损伤; 5、无论大小尺寸、复杂形状均可检测鉴定; This metallic material discriminator is a hand-held handpiece identification device that is easy to identify by contact of the probe with the material to be inspected. First, the characteristics of 1, the use of steel material thermoelectromotive force, in a short period of time can come to test results; 2, identification of various metal materials is very convenient; 3, simple operation, does not require skilled technology; 4, No damage; 5, regardless of size, complex shapes can be detected;
