Model Number: HT-15/HT-16/HT-17/HT-18 Brand Name: TLEAD Key Specifications/Special Features: Features:1. Small, portable, accurate, light, weighing only 0.8kg, and can be easily operated like micrometer2. Works on practical hardness testing principle, having the same high testing precision as that of a bench type deviceIt has high testing accuracy complies with the ISO6508 standard, with an error of no more than 1.5HRC3. Comprising the main unit and holder, the hardness tester can either be used on the table or easily carried to workshops4. It is fast, taking only 10 seconds to finish a test5. Value can be conveniently read out6. Can be adopted for testing fine, long, small and irregular parts. suitable for testing finished or semi-finished batching processed workpiece one by one7. The internal and external surface hardness of steel tubes can be tested by the Rockwell portable hardness tester8. Suits parts with small bearing surface, in particular
