HV-1000型显微硬度计
Model HV-1000 Micro Hardness Tester
HV-1000型显微硬度计是采用精密机械技术和光电技术的新型显微维氏和努氏硬度测试仪器。
该机外观新颖，采用微机控制，通过软健能调节测量光源强弱，并能预置试验力保持时间，以LED显示。该机采用独特的压痕测量转换和测微目镜一次测量读数机构。使用方便，测量精度高。
硬度计还可根据用户特殊要求配制摄影装置，能对所测压痕和材料金相组织进行拍摄。知用于测定微小、薄形试件、表面渗镀层等试件的显微硬度和测定玻璃、陶瓷。玛瑙、宝石等脆性材料的显微硬度，是科研机构、工厂及质监部门进行材料研究和检测的理想硬度测试仪器。
Model HV-1000 micro hardness tester is a novel type micro Vicker’s and Knoop’s hardness testing apparatus which adopts precise mechanical technique and photoelectrical technique.
The cofiguration of this tester which adopts micro-computer to control is novel, by means of adjusting the soft key, the tester is able to adjust and measure either strong or weak light source, and is capable to pressure holding time of the test load and is displayed by LED. This tester adopts peculiar indentation measuring, inverting and read mechanism through measuring once by the micrometer eyepiece. It is easy to use , and high precision in measurement.
