5.1 Measurement Principle and Impact Device

The LS252D utilizes a D-type impact device, which is ideal for measuring metal hardness in narrow spaces such as grooves or gears. The device measures the rebound of an impact body to determine hardness.

Figure 5.1: The D-type impact device, designed for precise measurements in various metallic materials.

For accurate measurements, the measured object should have a minimum mass of 5 kg and a minimum thickness of 25 mm. If the weight or thickness does not meet these requirements, the object must be coupled to a solid support for testing. The minimum thickness of the measured object after coupling is 3mm.

5.2 360° Measurement and Directional Sensor

The LS252D features a built-in directional sensor that automatically compensates for angle errors, ensuring accurate 360° measurements. This allows for flexible testing in various orientations without manual adjustment.

Figure 5.3: The internal directional sensor automatically adjusts for various measurement angles.

5.3 Hardness Scale Conversions

The LS252D can switch between various hardness scales, including Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), and Rockwell (HRA/HRB/HRC) without requiring manual lookup tables. This is facilitated by its dual-coil technology.
