We offer digital leeb hardness tester is developed leeb hardness measurement principle based on the internationally popular metal material hardness tester. It has high accuracy, small size, easy to operate, and a wide range of measurement, especially for large, heavy-duty malleable pieces, example: roll turbine shaft, and applied to the components already installed and can not be demolished, for example, : site hardness testing of pressure vessels, turbine units and other equipment. Leeb hardness tester is widely used in petrochemical, aerospace, electric power, gas, automotive, shipbuilding, railways, machinery manufacturing and other industries.Measurement accuracy of 8hl ( hld=800 5 point arithmetic average )operating temperature040storage temperature-2050operating voltage4.7v6.0vpower supply4 section 1100mah rechargeable batterycharging power: not more than 200maweight: 580g (with d impact device)host dimension: 233 91 31 (mm)specifications: 40 44 rolls of printing paper printing paperhttp:www.shcaliper.com
