HST-L253 Multi-probe Leeb Hardness Tester
HST-L253 Multi-probe leeb hardness tester
Support DDLDCC four kinds of impact devices
Optional blue tooth wireless printer to quickly print measurement results
Double-coil digital probe, accurate measurement
Automatic switching of various hardness standards, eliminating the cumbersome manual table lookup
Built-in orientation sensor and 360-degree impact mitigation for the probe
HST-L253 is a split-type Leeb Hardness Tester. The probe and the host are connected by aviation plugs, and the host is capable of automatically identifying the impact device. The instrument adopts advanced digital double-coil probe technology, which provides precise measurement results and great interference-resistance. Providing a variety of hardness scales , such as Leeb scale (HL), Vickers scale (HV), Brinell scale (HB), Shore scale (HS), Rockwell scale (HRA/HRB/HRC), and they can make a mutual conversion to avoid cumbersome manual calculation. Besides the hardness, the instrument can measure the strength of the materials. For various measuring needs, the instrument may be fitted with four different impact devices, D, DC, DL, and C.
