LEEB U912 Portable Leeb Hardness Tester metal case

overview

The instrument uses full Chinese display, menu-style operation, simple and convenient. This machine can directly display various hardness values such as Richter, Brinell, Rockwell, Vickers, Shore, etc. Small, portable, and highly reliable, the instrument is suitable for harsh operating environments and is resistant to vibration, shock, and electromagnetic interference.

Features

1. According to the Leeb hardness measurement principle, the Leeb HL measurement interface is displayed when the machine is turned on, which can detect a variety of metal materials with high precision.

2. The "Steel" material is supported, and when the "Forged Steel" specimen is tested with a D/DC type impact device, the HB value can be read directly, eliminating the need to manually check the table.

3. It is easy to switch to all hardness systems (HL, HB, HRB, HRC, HV, HS) and convert the measured values of each hardness system in parallel.

4. The graphic dot matrix LCD screen is used to provide rich information and intuitive.

5. Full Chinese display, menu-based operation, simple and convenient operation.

6. It has a high-brightness LED backlit display, which is convenient for use in low-light environments.

7. One main unit can be equipped with 5 different impact devices, and the type of impact device can be automatically identified. There is no need to recalibrate when replaced.

8. It can store up to 600 sets of hardness measurement data (30~1 impact times). Each set of data includes information such as a single measurement, an average value, the date of measurement, the direction of impact, the number of times, the material, the hardness system, etc.

9. The upper and lower limits of hardness values can be set in advance, and automatic alarms will be given when the range is exceeded, which is convenient for users to test in batches.

10. The power supply uses 2 alkaline batteries, which have power-saving functions such as automatic shutdown.

11. There is a residual power indicator icon on the LCD, prompting the user to replace the battery in time.

12. It has the function of calibration of the indicator software.

Scope of application

Installed mechanical or permanently assembled components.

Mould cavities, heavy workpieces, workpieces with limited measuring space.

Failure analysis of pressure vessels, turbine-generator sets and their equipment.

Material separation of bearings and other parts, metal material warehouse.

Rapid inspection of multiple measuring parts in a large area of large workpieces.

Applicable Materials

Steel & Cast Steel, Alloy Tool Steel, Stainless Steel, Grey Cast Iron, Ductile Iron, Cast Aluminium Alloy, Copper-Zinc Alloy (Brass), Copper-Tin Alloy (Bronze), Pure Copper, Forged Steel

Mainly used for:

1. The hardness testing of products in the process of mass production can meet the testing requirements with a set of general standards.

2. For hardness testing of annealing, tempering, quenching and other heat treatments, if there is a hardened layer in the selection, you need to pay attention to the thickness of the hardened layer, if the hardened layer is too thin, you need to choose a C-type impact device

3. When testing the hardness of the bearing, it is necessary to pay attention to the bearing diameter, if the diameter is too small, you need to choose a special-shaped support ring

4. When testing the hardness of the gear, if the gear is too small, you need to choose the DL impact device

5. When inspecting castings, if it is difficult to perform the finish, it is necessary to choose the G-type impact device.
