Working principle

With a certain quality of impact in the spring under the force of the impact surface of the sample, impact body impact velocity from the surface 1mm VA and VB rebound faster than that indicated

Leeb hardness. Electromagnetic theory, impact body impact device coil permanent magnet produces a voltage, this voltage is proportional to the speed of the impact body.

Formula: HL =1000xVB/VA Technical parameters

Measurement method: Leeb hardness measurement of hardness standard: Leeb HL, Brinell HB, Rockwell HRB, Rockwell HRC, Vickers HV, Shaw HS strength σ b measuring range:HLD(200-960)HRC(19.8-68.5)HRB(13.5-100)HB(30-651) HV (80-976) HS (26.4-99.5) σb (375-2639) Impact device: standard d, can selected C/G/DC/DL/D+15 shows value errors: errors is less than is equal to 6HLD (HLD=800), repeat sex errors is less than 6HLD (HLD=800 Shi) measurement direction: support vertical down, oblique Xia, level, oblique Shang, vertical up applies material: steel and cast, stainless steel, gray cast iron, ductile iron, cast aluminum, copper zinc alloy, Copper tin alloy, pure copper resolution: 1HL, 1HV, 1HB, 0.1HRB, 0.1HRC, 0.1HS displayed: high compared degrees paragraph code LCD screen (LED backlight) data storage: 100 Group (each group containing 1-7 a hardness value and the one average) communications interface: Bluetooth, USB print: Bluetooth Hot sensitive portable printer work power: two section 1.5V AA battery work temperature:-10 to + 50 ℃ instrument size: 153mmx76mmx37mm (HxWxD) weight: containing battery 280g standard: meet GB/T 17394-1998,ASTM A956 instrument configuration
