Jfe SH-21B-E2 Handy Hardness Tester

• Fast action, measures hardness in seconds.
• Practically undetectable measurement technique leaves indentations of 0.1mm2 allowing use on finished products.
• Displays hardness in HV (Vickers), HRC (Rockwell), HS (Shore) and HB (Brinnel) units.
• Measurement can be converted to tensile strength, N/mm2
• Readings not affected by surface underneath test sample.
• 2000 Reading data memory can be transferred to PC.
• Measuring Indentor Diamond indenter for Micro-Vickers (facing-to- surface angle of 136°)
• Testing Force SH-21-E2: Approx 2kgf (roughly 20N)
• Measuring Range

Rockwell hardness: HRC 10.0 - 70.0

Vickers hardness: HV 100 - 999

Shore hardness: HS 20.0 - 99.9

Brinell hardness: HB 85 - 550

• Resolution 1HV, 0.1HRC, 0.1HS, 1HB, 1N/mm2 (tensile strength)
