Request A Quote User Manual

The LS252DL is an all-in-one hardness tester that measures hardness according to the Leeb hardness measurement principle and can be used for hardness measurements on a wide range of metals. The instrument uses impact device DL and is suitable for testing in grooves or on gears where space is tight. It uses advanced dual coil technology for good repeatability and high accuracy. The probe with orientation sensor compensates for measurement errors in different impact directions automatically. The system has various hardness scales, which can be interchanged between Richter (HL), Vickers (HV), Brinell (HB), Shore (HS), Rockwell (HRA), Rockwell (HRB) and Rockwell (HRC) to avoid tedious manual calculations.

Features

Impact device DL

It is suitable for testing the hardness of metals in tight spaces such as recesses

Cutting-edge dual-coil technology

The technology brings the tester extraordinary measurement accuracy and good repeatability

Direction sensor inside the probe will compensate the measurement errors in different impact directions automatically

The instrument can measure at any angles. Featuring a built-in direction sensor, the probe can automatically compensate the measurement errors in different impact directions. Multi-angle measurement is easy

Impact device is made of Tungsten carbide

Impact device DL is partly made of Tungsten carbide, and its hardness is almost equal to the diamond

Conversions to different hardness scales

LS252DL hardness tester provides a variety of hardness scales, which can be converted between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS) and Rockwell (HRA/HRB/HRC)

Capable of measuring a wide range of metal materials

With 10 metal materials choices, including steel, alloy tool steel, stainless steel and grey cast iron, the instrument can be used in a wide range of applications and industries to meet the demands of everyday work
