Linshang LS255 Digital Webster Hardness Tester

LS255 Digital Webster Hardness Tester

LS255 Webster hardness tester; is a practical test device with a digital display that quickly measures the hardness of aluminum, brass, copper, mild steel, and other metal materials.
It is especially used in the quality control process of parts in the form of profiles, pipes, or sheets.

• The device's most significant feature; is its ability to perform measurements with excellent precision with its digital display, unlike its mechanical dial gauge counterparts on the market.

• The LS255 Webster hardness tester is ideal for quickly, non-destructively, and individually controlling materials such as metal profiles, sheets, and pipes in production, sales, and construction site environments.

• It features measurement technology based on the eddy current induction principle and offers high repeatability and precision.

• It supports 6 hardness systems such as Webster (HWA), Rockwell (HRE, HRF, HRB), Vickers (HV), and Brinell (HB), allowing easy conversion between these scales.

• With an Android-based smart mobile app, it is possible to store, export, and share test results in bulk.

• Thanks to its 0.1 HWA resolution, measurements are highly precise.

• The device can store 9 measurement data on its own display; more results can be recorded and reported via the app.

• It has an automatic data locking function; there is no need to fully press the handle while taking a measurement.

• It is small, portable, and lightweight; can be used with one hand. Suitable for rapid and non-damaging control in production areas, sales points, and construction sites.

• It features reference and hardness calibration technology that does not require disassembly; calibration can be completed by simply pressing the handle.

• Its body is made of anodized forged aluminum alloy material; it is comfortable to grip, resistant to wear and dirt.

• Package includes: LS255 device, charging cable, calibration block, manufacturer's test certificate.

• A standard Webster hardness block for measurement verification comes with the device; surface roughness and flatness comply with applicable regulations.

LS255 Webster hardness tester; is a highly practical and reliable device designed for quick, non-destructive, and individual measurement of metal profiles, sheets, and pipes in industrial environments such as production, sales, and construction sites.
It provides instant results with high precision measurements, and its durable structure and ergonomic design ensure long-term use in challenging conditions.
It plays an important role in quality control, production efficiency, and workplace safety processes.
