Description
JDR-150A Rockwell& Surface Rockwell (Double Rockwell) Hardness Tester
Main Features
- Direct reading of dial hardness value.
- The MRR(D)-150D1 type is automatic loading and unloading-keeping-unloading, with simple operation and no artificial operation error.
- The MRR(D)-150A1 is a manual loading and unloading load, its operation without power supply support.
- Stable performance, simple operation, convenient use.
- Optimized design of the mechanical structure, linear small circular arc appearance.
- Strong structure, good rigidity, reliability, durability, and high-test efficiency.
- It can be equipped with pressure head expansion hardness gauge.
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).
