RHL-49 Portable Leeb Hardness Tester for Steel Stainless Steel Aluminum Alloy

RHL-49 Portable Leeb Hardness Tester for Steel Stainless Steel Aluminum Alloy

一,Summary:

The Richter hardness measuring instrument, through technological innovation and continuous 72 hour factory aging treatment, makes the product performance more stable and the accuracy higher. The unique advantage of rhl-49 lies in the combination of two data processing schemes: a portable all Chinese self powered thermal high-speed printer and a humanized PC connected processing software. Due to the in-depth study of the mechanism of Leeb hardness, we can design and manufacture different impact devices and tooling fixtures according to different needs of customers.

二,Technical parameters:

三,Features:

1. Fully sealed metal shell, compact, portable, high reliability, suitable for harsh operating environment, strong resistance to vibration, impact and electromagnetic interference, solid and durable;

2. According to the principle of Leeb hardness measurement, a variety of metal materials can be tested. It has a wide range of measurement, has no shape restrictions on the measured workpiece, supports 360 o measurement direction, and has the function of starting the value indication software calibration, which can better ensure the applicability and accuracy of the data under different specifications and standards in any industry.

3. Support a variety of hardness tester systems, including Leeb (HL), Brinell (HB), Rockwell B (HRB), Rockwell C (HRC), Rockwell a (HRA), Vickers (HV) and shore (HS). Parallel conversion between hardness and hardness can be carried out before and after measurement.

4. Excellent compatibility. Seven impact devices do not need calibration and automatic identification. The price of special-shaped impact device and series of special-shaped support rings is reasonable to meet the maximum needs of different customers in different fields.

5. Full Chinese large screen 128 * 84 graphic dot matrix LCD liquid crystal display, with El backlight support, which is convenient for use in low light environment.

6. The main engine panel is operated in Chinese menu mode, and the circuit design reflects the humanized concept. One click can realize the arbitrary switching of material and hardness, which is simple and convenient.

7. With common 232 plug and play interface, the standard configuration is equipped with PC data processing software connected to the computer and micro on-site high-speed thermal printing device. Convenient, flexible and real-time processing of field data.

8. Store up to 600 groups of hardness measurement data (impact times 32 ~ 1) in large capacity. Each group of data includes single measurement value, average value, measurement date, impact direction, times, material, hardness system and other information. Connecting computers with software can also realize mass storage.

9. The upper and lower limits of the hardness value can be set in advance, and the alarm will be given automatically when the hardness value exceeds the range, which is convenient for users to meet the needs of batch testing.

10. Support "steel" materials. When testing "steel" samples with D / DC impact device, Hb value can be read directly without manual table checking.

11. It has energy-saving functions such as automatic sleep and automatic shutdown, low-power design, two AA No. 5 batteries for power supply, convenient replacement and stronger battery reliability.

12. Overall dimension: 132 x 76.2

13. Overall weight: 345g

四, Applicable materials:

Steel and cast steel, alloy tool steel, stainless steel, gray cast iron, nodular cast iron, cast aluminum alloy, copper zinc alloy (brass), copper tin alloy (bronze), pure copper.

五, Main application fields:

l. Mold cavity, core.

2. Bearings and other parts.

3. Failure analysis of pressure vessel, steam turbine generator unit and its equipment.

4. Heavy work pieces.

5. Installed mechanical or permanently assembled parts.

6. A workpiece with a narrow test space.

7. Formal original records of test results are required.

8. Material differentiation of metal material warehouse.

9. Rapid inspection of multiple measuring parts in a large range of large workpieces.

六, Working conditions:

Ambient temperature: operating temperature - 20 ~ + 60 ℃; Storage temperature: - 30 ℃ ~ + 60 ℃

Relative humidity ≤ 90%;

There is no strong vibration, strong magnetic field, corrosive medium and serious dust in the surrounding environment.

七, Startup display and brief description:

After startup, it will automatically enter the main display interface, as shown in the following figure:

1. Battery power: displays the remaining power.

2. Impact direction: current impact direction.

3. Average value: appears when the average value is displayed after reaching the set impact times.

4. Hardness system: the hardness system of the current measured value.

5. Measured value: current single measured value (no average value prompt), current average value (with average value prompt).

6. The display indicates that the conversion or measurement range is exceeded and that it is lower than the conversion or measurement range.

7. Material: the currently set material.

8. Impact times: the completed impact times are displayed during measurement. The set impact times are displayed when the impact times are set with the times shortcut key. The corresponding times of a single measurement value are displayed when browsing a single measurement value.

八, Data processing software: (optional)
