Features:
1. Precision conforms to GB/T230.2, ISO 6508-2 and ASTM E18.
2. Measuring head may move upwards and downwards, clamp the work piece and finish the hardness test automatically.
3. Automatically remove the oxidation-layer on the surface of work piece, and the surface removing depth is adjustable.
4. The first test point is effective. The measured hardness value may be converted to other hardness scales automatically.
5. Special software may store the test data in large capacity. It can also carry out data statistics, editing and analysing, etc.
