LS252DL(Impact device DL) Leeb Hardness Tester Features and Operation
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.
The instrument uses the impact device DL with a wide choice of built-in metal materials to suit the needs of different metal hardness tests.

Qualifications and standards
The hardness tester conforms to the following standards:
Loading: Push down the loading sleeve of the probe to lock the impact body.
Positioning: Press the probe firmly against the surface of the object to be measured and keep it still.
Measurement: Press the release button on the top of the probe to measure the hardness of the object.
When measuring, the distance between any two indentations should not be less than 3mm, and the distance between the center of the indentation and the edge of the object to be measured should not be less than 5mm.
After use, the impact body should be loosened.
The use of various lubricants is strictly prohibited in the impact device.
What is the thinnest thickness a durometer can measure and what is the thinnest thickness after coupling?
Leeb hardness tester is only suitable for large and heavy workpieces, small and thin parts must be coupled to a solid support for testing; DL-type impact device is measured by the minimum mass of 5kg, the minimum thickness of 25mm, if the weight or thickness does not meet the requirements, must be coupled to a solid support for testing, coupled to the minimum thickness of the measured object is 3mm.
