摘要： The invention relates to a material hardness testing instrument, specifically to a portable digital display hardness tester, comprising a magnetic chuck, a support, a force measuring device, an indenter, an electronic circuit board, a digital display, and a force applying and indentation depth measuring device consisting of a hand wheel, a rotary encoder and a micrometric screw pair. The support is equipped with the rotary encoder. The micrometric nut is installed in a hole. The digital display is located in the front. The support is fixed on the magnetic chuck. The micrometric nut is internally provided with the micrometric screw. The rotating shaft of the rotary encoder is connected with the micrometric screw and rotates along with the micrometric screw. The upper end of the micrometric screw is connected with the hand wheel, while the lower end is connected with the force measuring device. The lower end of the force measuring device is connected with the indenter. The hand wheel, the micrometric screw, the force measuring device and the indenter are connected and coaxial, capable of moving axially along with the rotation of the hand wheel. The invention is simply structured, convenient in reading, easy to operate, high in accuracy, capable of being applied to the onsite, quick hardness testing of large parts, and capable of testing the Brinell hardness and Vickers hardness through depth measurement.
