Overview
The LS253DC Leeb hardness tester is a split instrument. The probe and the host are connected through an aviation plug, and the host can intelligently identify the Impact device. It adopts digital dual-coil probe technology, which has strong anti-interference ability and accurate measurement performance. Built-in a variety of Hardness standards, it can automatically convert between Richter (HL), Vickers (HV), Brinell (HB), Shore (HS), Rockwell (HRA, HRB, HRC) and tensile strength (sigma b) without manual table lookup. The instrument provides two measurement modes, statistical and QC, and supports a variety of Impact device options to adapt to different measurement needs.
Features
1. The host and the Impact device are connected through an aviation plug, which can be freely matched with four Impact devices: D, DC, DL, and C to meet the diverse measurement environment.
2. Connect the mobile app through Bluetooth to realize multiple sets of data storage and sharing functions.
3. Adopt double coil technology to ensure high Measurement accuracy and good Repeatability.
4. The probe has a built-in Direction Sensor, which automatically compensates for measurement errors in different directions and supports 360 ° all-round measurement.
5. Built-in a variety of Hardness standards, automatic conversion eliminates the tediousness of manual table checking.
6. Measurement accuracy up to +/- 6HL, to ensure that by the national trusted Measurement Institute detection.
7. Connect the thermal printer through Bluetooth, and print the measurement results directly on site.
8. Provide QC mode and statistical mode. The statistical mode automatically calculates the MAX Maximum, MIN Minimum and average value of the last 9 sets of data. The QC mode can set the upper and lower limits for batch inspection of incoming materials.
9. Adopt low-power technology and dynamic sleep algorithm, with automatic shutdown function, energy saving and environmental protection.
10. Digital probe technology enhances anti-jamming capabilities.
11. Large LCD backlit display, menu operation, easy to understand information.
12. Equipped with standard Hardness block, users can calibrate by themselves.
Principle
The instrument adopts digital dual-coil probe technology to carry out Hardness measurement of metal materials through the Impact device, and the built-in Direction Sensor of the probe automatically compensates for measurement errors. The host intelligently recognizes the Impact device and uses the built-in algorithm to automatically convert between various Hardness standards to ensure accurate and reliable measurement results.
Applications
The hardness testing of materials such as machine tool guides, automobile chassis, heavy workpieces, mold cavities, bearings, Pressure Vessels, installed machinery or assembled parts helps manufacturers to conduct product mass inspection, rational process and product mass analysis.

GB/T 13794.1、GB/T 13794.2、GB/T 13794.4、JB/T 9378-2001、JJG 747-1999
Steps
1. Connect the probe and the host using an aviation plug.
2. Turn on the instrument power supply, and the host automatically recognizes the Impact device.
3. Select Measurement mode (Statistical mode or QC mode).
4. Impact device aligned with the measured material for measurement.
5. The instrument automatically displays and stores the measurement results, and can share or print data through Bluetooth connection APP or printer.
Notice
• Operating temperature range is -10~ 50 ℃, relative humidity 0~ 85% (no condensation).
Storage Temperature range is -10~ 60 ℃, relative humidity 0~ 85% (no condensation).
• Make sure the battery is fully charged before use, it is recommended to use 2 AA alkaline dry batteries.
• Keep the probe in vertical contact with the measured material during measurement to avoid tilting affecting the accuracy.
• Regularly calibrate with standard Hardness blocks to ensure measurement accuracy.
• In the dim environment of light rays, the backlight display can be turned on, but pay attention to energy saving use.
• Avoid use in a strong electromagnetic interference environment to prevent affecting the measurement results.
