奥龙HR-150AⅡ洛氏硬度计

HR-150AⅡ洛氏硬度计

HR-150AⅡ型洛氏硬度计选用全进口LCD数显表，代替了指针式表盘，消除了读数和操作误差，提高了显示精度和重复性精度，该机外观新颖，操作方便。适用于金属材料的洛氏硬度试验。施加试验力的速度由缓冲器来调节，试验力的变换采用变荷手轮的转换而获得，因而具有操作简便，性能稳定，使用广泛等特点。

原理：

    洛氏硬度适用于各种金属材料的硬度测定。它的试验原理是在初试验力及总试验力先后作用下，将压头压入试样表面，卸除主试验力，测量保留初试验力时的压痕残余深度。

硬度计的技术参数：

初试验力：98.07N，允差±2.0%

总试验力：588.4N、980.7N、1471N，允差±1.0%

压头规格：金刚石圆锥洛氏压头

φ1.5875mm球压头      

被测试件允许最大高度：170mm

压头中心到机身距离：165mm

硬度计外形尺寸（长×宽×高）510×212×700m

仪器重量约：85kg

Product Name: HR-150A Ⅱ Rockwell hardness tester

Model: HR-150A Ⅱ 

Details: HR-150AⅡ Rockwell hardness tester selection all imported LCD digital display, instead of the dial pointer, eliminating the reading and operating errors and improve the accuracy and repeatability of the display, the aircraft the appearance of new, easy to operate. Rockwell hardness test applies to metallic materials. Speed test force exerted by the buffer to adjust, test force transformation with variable charge handwheel conversion gain, which is a simple, stable performance, widely used and so on.

Principle:

Rockwell hardness measurement applies to all kinds of metal materials. Its principle is at the beginning of trial test force and total test force has the role of the indenter into the surface of the sample, removable main test force, measuring the depth of the indentation residual reserves at the beginning of the test force.

Technical parameters:

Preliminary test force: 98.07N, tolerance ± 2.0% 

Total test force: 588.4N, 980.7N, 1471N, tolerance ± 1.0%
