Overview
LS253 is a split Leeb hardness tester. The probe and the host are connected by aviation plug, and the host intelligently recognizes the Impact device. The instrument adopts excellent digital dual-coil probe technology, which has strong anti-interference ability and accurate measurement results. Built-in a variety of Hardness standards, which can be converted between Richter (HL), Vickers (HV), Brinell (HB), Shaw (HS), Rockwell (HRA), Rockwell (HRB), Rockwell (HRC) and tensile strength (sigma b) to avoid cumbersome manual table conversion. The instrument has 2 Measurement modes. The MAX Maximum, MIN Minimum and Average can be calculated through the statistical mode, and the incoming material can be detected in batches through the QC mode. The instrument can be equipped with four different Impact devices D, DC, DL, C, which are suitable for different measurement needs.
Features
1. The host and the Impact device are connected by aviation plugs, and one host can be freely matched with four Impact devices: D, DC, DL, and C to meet the needs of different measurement environments.
2. The instrument is connected to the mobile app through Bluetooth, which can realize multiple sets of data storage, and the measurement data can also be shared.
3. Excellent Dual Coil Technology with Good Measurement accuracy and Repeatability.
4. The probe has a built-in Direction Sensor, which can automatically compensate for measurement errors in different directions and achieve 360 ° comprehensive worry-free measurement.
5. The instrument has a variety of built-in Hardness standards, which can be converted to each other in Richter (HL), Vickers (HV), Brinell (HB), Shaw (HS), Rockwell (HRA), Rockwell (HRB), Rockwell (HRC) and intensity (SB), eliminating the tedious steps of manual table checking.
6. Measurement accuracy of the instrument can reach +/- 6HL, measurement accuracy, to ensure that through the national trusted Measurement Institute detection.
7. The instrument is connected to the thermal printer through Bluetooth, and the measurement results can be directly printed on site.
8. The instrument has two measurement modes: QC mode and statistical mode to choose from to meet different measurement needs. The statistical mode can automatically count the MAX Maximum, MIN Minimum and average value of the 9 sets of data recently measured. The QC mode can detect whether the incoming material is qualified in batches through the setting of the upper and lower limits.
9. Low-power technology, dynamic sleep algorithm, with automatic shutdown function, making the instrument more energy-efficient.
10. Adopting digital probe technology, it has strong anti-interference capabilities.
11. Large LCD backlight display, can be used in dim environments with rays of light, menu operation, and the information is intuitive and easy to understand.
12. Equipped with standard Hardness block, users can calibrate by themselves.
Principle
Hardness measurement is carried out using digital dual coil probe technology. The built-in Direction Sensor automatically compensates for measurement errors in different directions. The host is connected to the Impact device through an aviation plug to intelligently identify the type of Impact device to achieve accurate measurement and data conversion.
Applications
Machine tool guides, automotive chassis, heavy workpieces, mold cavities, bearings, Pressure Vessels and installed machinery or assembly parts and other materials hardness testing
