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.
