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. |
| 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 | The instrument adopts eddy current induction principle measurement technology, its resolution is as high as 0.1HWA, making measurement more accurate. |
