奥龙HR-150DT Ⅲ电动洛氏硬度计

HR-150DT Ⅲ电动洛氏硬度计

HR-150DT Ⅲ型电动洛氏硬度计采用自动加卸试验力机构，装有可调总试验力保持时间的电位器，试验力变换由变荷手轮的旋转而获得，所以操作简便迅速，除度盘对零外，没有人为的操作误差，具有很高的灵敏度，稳定性，适用于车间和实验室。
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。
特点： 具有洛氏硬度标尺的选用；具有硬度标尺转换选择；硬度测试保持时间可从0～99s之间选择；具有复位功能；硬度测试结果打印输出；具有RS-232C串行通讯口，供用户扩展功能。

Product Name: Model HR-150DT Ⅲ Rockwell Hardness Tester

Model: HR-150DT Ⅲ

Detailed: Model HR-150DT Ⅲ Rockwell Hardness Tester automatic unloading mechanism with adjustable total test force dwell time potentiometer, rotary converters test force transformation by the Dutch handwheel obtained, so the operation easily and quickly , in addition to dial zero, there is no human operator error, high sensitivity, stability, suitable for workshops and laboratories. 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. Features: Optional with Rockwell hardness scale; having hardness scale conversion option; hardness test hold time can be selected from between 0 ~ 99s; having reset function; hardness test results printout; has RS-232C serial communication port for user extensions .

Hardness technical parameters: Preliminary test force: 98.07N, tolerance ± 2.0% Total test force: 588.4N, 980.7N, 1471N, tolerance ± 1.0% Head Specifications: Rockwell diamond cone indenter φ1.5875mm ball indenter Be allowed to test the maximum height: 170mm Indenter center to the fuselage: 165mm Total test force dwell time (S): 0-30 Hardness Dimensions (L × W × H) 510 × 212 × 700m Instrument weight about: 85kg Hardness range HRA: 20 ~ 88 HRB: 20 ~ 100 HRC: 20 ~ 70
