Model. 900-345
The Model 900-345 Surface Rockwell Hardness Tester is used to measure the surface Rockwell hardness value of thin, soft materials. The 900-345 durometer is designed to be durable, providing high sensitivity and accurate measurements. Following the ASTM E-18 Standard for Surface Rockwell Hardness, the 900-345 Rockwell Hardness Tester provides excellent repeatability in all surface Rockwell measurements (see table below). This instrument is suitable for use in any environment, including: heat treatment equipment, tool magazines, workshops, and testing laboratories.

Features
Direct reading from the dial
The indication value is stable and the accuracy is high
Automatic selection and automatic switching of main loads
Implements the American standard ASTM E-18
It can be used in laboratories, workshops, tool rooms, etc
