Product Description
The HR-150A Manual Rockwell Hardness Tester is a widely used, cost-effective mechanical testing instrument for hardness measurement.
It adopts a manual loading system that does not require power, providing stable and consistent test results under various working conditions.
Hardness values are read directly from the dial indicator, which reacts sensitively and ensures high precision.
The instrument's shell is made through a single-piece sand-casting process, offering excellent structural stability and resistance to deformation.
Its surface features automotive-grade enamel coating, which is scratch-resistant and remains glossy even after long-term use.
This model combines simplicity, reliability, and precision, making it a practical and economical choice for both industrial inspection and educational laboratories.
