Main function

According to the principle of Leeb hardness measurement, the Leeb measurement interface is displayed when turned on.

Menu operation, rich in information and intuitive.

High-brightness LED backlight is convenient for use in dark environments.

Automatic sleep, automatic shutdown and other power-saving functions, low-power design.

The lithium battery is charged and can work continuously for 10 hours.

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.

Main purpose

1. Measure large, thick, heavy and rough surface castings and forgings;

2. Hardness testing of heat treatment such as annealing, tempering, and quenching, the thickness of the hardened layer is too thin;

3. When testing castings and forgings, it is difficult to deal with the finish.

Leeb Hardness Tester meets the standards

1. GB/T 17394.1-2014 "Metallic Materials, Leeb Hardness Test, Part 1: Test Methods"

2. GB/T 17394.2-2012 "Metallic Materials, Leeb Hardness Test, Part 2: Inspection and Calibration of Hardness Tester"

3. GB/T 17394.3-2012 "Metal Materials, Leeb Hardness Test, Part 4: Calibration of Standard Hardness Blocks"

4. GB/T 17394.4-2014 "Metal Materials, Leeb Hardness Test, Part 4: Standard Value Conversion Table"

5. Design basis standard: "Leeb Hardness Tester technical conditions" JB/T 9378-2001

Requirements for the surface of the sample being tested

The condition of the specimen surface shall meet the relevant requirements in the test range table.

The surface temperature of the sample should not be too high and should be less than 120 ℃.

The surface roughness of the sample should not be too large, otherwise it will cause measurement errors. The measured surface of the sample is exposed to metallic luster, and it is flat, smooth and free of oil stains.

Specimen weight requirements: For heavy-duty specimens greater than 5kg, no support is required; specimens weighing 2-5kg, specimens with overhanging parts and thin-walled specimens should be supported by objects during testing to avoid deformation caused by impact force., bending and movement. For medium-sized samples, place them on a flat, firm plane, and place the samples smoothly without shaking.

Curved sample: The test surface of the sample is flat. When the radius of curvature R of the measured surface is less than 30mm (D, DC, C, DL type impact device) and less than 50mm (G type impact device), a small support ring or a special-shaped support ring should be used during testing.

The sample should have the corresponding thickness, and the small thickness of the sample should meet the requirements of the impact device table.

For specimens with a surface hardening layer, the depth of the hardening layer shall comply with the requirements of the impact device table.

coupling

1) For light samples, it needs to be tightly coupled with a solid support, the two coupling surfaces need to be flat and smooth, the amount of coupling agent should not be too much, and the test direction needs to be perpendicular to the coupling plane;

2) When the sample is a large area plate, a long rod, or a curved piece, even if the weight and thickness are large, the deformation and instability of the sample may still be caused, resulting in inaccurate test values, so it should be firmly fixed or supported on the back of the test point.

The magnetism of the sample itself should be less than 30 Gauss.
