Overview
The LS253D Leeb hardness tester is a split instrument. The probe and the host are connected by 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 results. Built-in a variety of Hardness standards can be converted between Richter (HL), Vickers (HV), Brinell (HB), Shaw (HS), Rockwell (HRA, HRB, HRC) and tensile strength (sigma b) to avoid cumbersome manual table lookup. The instrument provides 2 Measurement modes: Statistical mode can calculate MAX Maximum, MIN Minimum and average value, and QC mode is used to detect whether the incoming material is qualified in batches. Impact devices D, DC, DL and C can be selected to meet different measurement needs.
Features
1. The host and the Impact device are connected by an aviation plug, which can be freely matched with four Impact devices: D, DC, DL, and C to meet the needs of different measurement environments.
2. Connect the mobile app through Bluetooth to realize multi-group data storage and sharing.
3. Adopt double coil technology, Measurement accuracy is high, Repeatability is good.
4. The probe has a built-in Direction Sensor, which automatically compensates for measurement errors in different directions and supports 360 ° measurement.
5. Built-in a variety of Hardness standards, including HL, HV, HB, HS, HRA, HRB, HRC and SB, automatically convert the free table.
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 can automatically count the MAX Maximum, MIN Minimum and average value of the last 9 sets of data, and the QC mode can set the upper and lower limits for batch detection 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 has strong anti-interference capabilities.
11. Large LCD backlight display, can be used in dim environments with rays of light, and the menu operation is intuitive and easy to understand.
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. The built-in Direction Sensor of the probe automatically compensates for measurement errors in different directions to achieve 360 ° comprehensive measurement. The host intelligently recognizes the type of Impact device and automatically converts between various Hardness standards through built-in algorithms, eliminating the need for manual table checking to ensure accurate measurement and anti-interference.
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.
Standards
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. Select and install the appropriate Impact device (Type D, DC, DL, or C).
3. Turn on the instrument and select Measurement mode (statistical mode or QC mode) as needed.
4. In statistical mode, the instrument automatically calculates the MAX Maximum, MIN Minimum, and Average of the last 9 sets of data.
5. In QC mode, set the upper and lower limits to check whether the incoming materials are qualified in batches.
6. Connect the mobile app or thermal printer through Bluetooth for data storage, sharing or printing.
7. Use standard Hardness blocks for user self-calibrating.
Notice
• Operating temperature of the instrument is -10~ 50 ℃, humidity 0~ 85% RH (no condensation).
Storage temperature is -10~ 60 ℃, humidity is 0~ 85% RH (no condensation).
• Use 2 AA alkaline dry batteries for power supply, pay attention to battery replacement.
• Backlit displays can be used in dim environments with low rays of light.
• Ensure that the Impact device is properly installed and connected to avoid measurement errors.
• Regularly use standard Hardness block calibrated instruments to maintain accuracy.
