LS253 Multi-probe Digital Leeb Hardness Tester Double-coil Probe Technology Hardness Meter Aluminum Metal Leeb Hardness Tester
LS253 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.

Features:
- LS253 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 is connected to the mobile phone APP through Bluetooth to realize multiple sets of data storage, and the measurement data can be shared.
- Using advanced dual-coil technology, it has good measurement accuracy and repeatability
- The probe contains an integrated direction sensor that accomplishes 360° all-around worry-free measurement by automatically compensating measurement mistakes in various direction
- LS253 hardness tester provides a variety of hardness scales, which can be converted between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS) and Rockwell (HRA/HRB/HRC) eliminating the cumbersome steps of manual table lookup.
- Two measurement modes, QC mode and statistical mode, can be selected to meet different measurement needs. The tester can automatically count the maximum value, minimum value, and average value of the lastest 9 measured values. The tester can set the upper ad lower limits and judge whether the hardness of the materials is qualified which is convienent for batch inspection
