HRS-150A Manual Digital Display Rockwell Hardness Tester
HRS-45A Manual Digital Display Surface Rockwell Hardness Tester
(The First Digital Display Head Type in China)
Main Features
- The latest independent dial digital LCD display, button cell power supply, easy maintenance.
- It has ultra-low power consumption, long battery life and can be used normally for as long as one year.
- This machine can be operated in any place without grid power supply (External power supply is not required).
- Manual loading and unloading-keeping-unloading, simple operation.
- Hardness automatic display, high accuracy, small indication resolution, no artificial operation error.
- The digital display head has an output interface. Testers can choose external micro printer.
- Print report content: hardness average, maximum and minimum, hardness discreteness.
- It has an automatic conversion with other hardness. (HB, HV, etc.)
Application Range
- Rockwell: It is used to measure Rockwell hardness of ferrous, nonferrous metals and nonmetallic materials. It is suitable for measuring Rockwell hardness of heat treatment materials such as quenching and modulation.
- Surface Rockwell: It is used to measure the surface Rockwell hardness of the ferrous metal, alloy steel, hard alloy, and metal after surface treatment (carburizing, nitriding and electroplating).
