Description
Description
The Linshang LS252D portable Leeb hardness tester integrates a D impact device and an OLED display in one pen-shaped body. It is intended for rebound hardness checks on prepared metal surfaces when a compact instrument is useful for repeated measurements around a workshop or installed component.
D impact device for general metal checks
Use the material menu to match the component, then select an available hardness scale. The tester supports Leeb readings and material-dependent conversions to HV, HB, HS and Rockwell scales. Steel, stainless steel, cast iron and other listed metal groups can be selected; the conversion range depends on the chosen material.
The direction sensor compensates for the orientation of the impact device, so you can work at different angles while keeping the support ring firmly seated. For unsupported testing, the component must weigh at least 5 kg and be at least 25 mm thick. Couple smaller or thinner workpieces to a solid support before measuring.
Readings, calibration and charging
The OLED screen displays the measured value, while the history view retains nine recent records after power-off. Calibrate using an appropriate standard hardness block, then use consistent material selection and support conditions when comparing parts. The internal 3.7 V, 250 mAh lithium battery charges through USB.

Prepare, load and release
Expose a smooth, clean metal surface without oil or grease. Push down the loading sleeve to lock the impact body, place the tester firmly against the surface, and press the release button. Each impact leaves an indentation. Allow at least 3 mm between indentation centers and 5 mm from the center to an edge.
Converted hardness values are a convenience for supported material groups, rather than direct Rockwell or Vickers tests. Release the impact body after use and avoid lubricants inside the mechanism.
