True color screen Leeb hardness tester is innovation designed basing on the intensive study of the Leeb hardness measurement principle. On the basis of existing data table, four kinds of material hardness system are added: D type impact device alloy tool steel increased the HRA, HB;Cast aluminum alloy HV items;C impact device increased the cast aluminum alloy HV items. And, it is worth mentioning that the function of "user materials" is developed, which not only implements the user demand for special material testing but also expand greatly the Leeb durometer application range.All above is exclusive for all instruments at home and abroad.
This instrument conforms to the below regulation and rules:
Domestic standard:GB/T 17394 (1998)、JB/T 9378 (2001)、JJG 747 (1999)
International standard:ASTM A956 (2006)、CNAL T0299 (2008)、JIS B7731 (2000)、DIN 50156 (2007)、DGZfP Guideline MC 1 (2008)、VDI / VDE Guideline 2616 Paper 1 (2002)、ISO 18625 (2003)
1. Four kinds of material hardness system are added by the market requirement: D type impact device alloy tool steel increased the HRA, HB;Cast aluminum alloy HV items;C impact device increased the cast aluminum alloy HV items. The "user materials" function ensures it’d test all metal material hardness theoretically.
2. The high strength import plastic alloy enclosure, streamlined appearance design, more portable and durable.Suitable for bad operating environment. Resistance to vibration, shock, and electromagnetic interference.
3.According to the Leeb hardness measurement principle, it can test a variety of metal materials. With wide measuring range, there is no limit to the shape of workpiece and support 360 DHS measuring direction. It also has a boot value software calibration function, which can guarantee the data applicable and accurate under different norms and standards in any industry.
4.It not only can switch among seven hardness systems Leebs (HL), brinell (HB), rockwell B (HRB), rockwell C (HRC), rockwell (HRA), vickers (HV) and shaw (HS), but also can realize the transformation between the hardness and strength.
5.Excellent compatibility, automatic identification of seven impact devices without calibration. Meet the maximum demand of different clients in various fields.
6. Adopt large screen true color liquid crystal displays and WOINDOWS interface. Lively and vivid content, clear and intuitive information.Can adjust the LCD brightness freely, convenient to operate in dark environment.
7. Liquid crystal indicates the remaining power icon, prompt the user charge in time.
8.Hardness value can be preset upper and lower limit. Automatic alarm if beyond the scope. Convenient for users batch testing.
9.Power supply adopts integrated lithium battery and can work continuously not less than 100 hours, with automatic power saving function, automatic standby&shutdown, etc.
