HRS-150型数显洛氏硬度计
Model HRS-150 Digital Rockwell Hardness Tester
HRS-150型数显洛氏硬度计是机电一体化的硬度测试仪器。该机外观新颖，采用微机控制，硬度值以数字直接显示。升降螺杆与旋轮间自动反馈锁合，外接打印机，除试台升降外，完全实现了自动化，消除了操作和读数误差。
该硬度计适用于黑色金属、有色金属和非金属材料的硬度测定。
The Model HRS-150 digital Rockwell hardness tester is an organic whole of mechanical and electrical hardness testing instrument, with its novel appearance, directly obseverd digital display device and micro-computer control lifting and lowering screwied and automatic feedback lock among rotary wheels, connecting outside to the printer, full realizes the automatic. That completely eliminates error in thoes operations and reading.
It can used to measure the Rockwell hardness of ferrous, non-ferrous metals and plastic materials.
