High precision hardness tester
Features
1.Applicable materials: steel and cast steel, alloy tool steel, stainless steel, gray cast iron, ductile iron, cast aluminum alloy, copper-zinc alloy (brass),
copper-tin alloy (bronze), pure copper, forged steel.
2.According to the Leeb hardness measurement principle, various metal materials can be detected. Wide measurement range, no shape limitation for measured workpieces,supports 360° measurement direction,
and has power-on display software calibration function, ensuring data complies with different industry standards.
3.Supports multiple hardness scales: Leeb (HL), Brinell (HB), Rockwell B (HRC), Rockwell A (HRA), Vickers (HV), Shore (HS).
Parallel conversion between hardness scales can be performed before and after measurement.
4.Good compatibility, seven impact devices automatically recognized without calibration. Special-shaped impact devices and series of special-shaped support rings at reasonable prices,
meeting diverse customer needs in different fields.
5.Full Chinese menu operation on host panel, humanized circuit design, one-key switching between materials and hardness scales, simple and convenient.
6.Standard 232 plug-and-play interface, PC data processing software for computer connection and high-speed thermal printing device for on-site use.
Convenient and flexible for immediate on-site data processing.
7.Large capacity storage up to 600 groups (impact times 32~1) of hardness measurement data, each group includes single measurement data, average value, measurement date,
impact direction, times, material, hardness scale and other information. Computer connection via software enables massive storage.
8.Pre-set upper and lower hardness limits, automatic alarm when out of range, convenient for batch testing needs.
9.Supports "forged steel" material, when testing "forged steel" samples with D/DC impact device, HB value can be read directly without manual table lookup.
10.Energy-saving functions like auto sleep and auto shutdown, low power design, powered by 2 AA batteries, easy to replace with better battery reliability.
