LS255 Webster Hardness Tester
Digital display, easy operation, accurate measurement
Digital display design, 0.1HWA high resolution
Automatic data locking, easy to read
Providing a variety of hardness scales to switch, no more tedious manual check table
No-disassembly reference calibration and hardness calibration technology
High precision, pass authoritative metrology inspection
The Webster hardness tester based on Webster hardness measurement principle, suitable for aluminium alloy, brass, copper, soft steel and other metal materials hardness measurement. It's particularly suitable for production, sales and construction site batch of metal profiles, plates, tubes, etc. to carry out rapid, non-destructive, piece-by-piece qualification inspection. The instrument adopts eddy current induction principle measurement technology, with good repeatability and measurement accuracy. It has a variety of built-in hardness systems, which can be converted between Webster (HWA), Rockwell (HRE), Rockwell (HRF), Rockwell (HRB), Vickers (HV) and Brinell (HB).

Features
Digital display
The top of the instrument is equipped with an OLED screen, which is easy to read and avoids errors caused by observing the dial with the naked eyes.
Data auto-locking function
The instrument is equipped with an automatic data-locking function, no need to press the handle all the way down when taking a reading.
Providing a variety of hardness scales
The instrument built-in six kinds of hardness scales, which can be converted between Webster (HWA), Rockwell (HRE), Rockwell (HRF), Rockwell (HRB), Vickers (HV) and Brinell (HB), no more tedious manual check table.
No-disassembly reference calibration and hardness calibration technology
The instrument has a disassembly-free reference calibration function, directly press the handle to complete it. Users can also eliminate test errors by calibrating standard block, which is easier and faster than traditional Webster hardness tester.
Reference Calibration
Calibration
High precision and good repeatability
The accuracy of the instrument is ±0.5HWA, and the repeatability is up to 0.5HWA, which ensures that it can pass the inspection of the authoritative metrology institute.
9 sets of data can be stored
Built-in memory chip, the instrument can store 9 groups of measurement results, meeting user's needs for multiple measurements of the measured object.
High resolution of 0.1 HWA
