Description
Product Introduction:
The XHRTL-150Z fully automatic color touchscreen digital Rockwell hardness tester is our company’s new-generation, multifunctional, high‑precision, and highly stable automated instrument. It features a modern design with an integrally cast housing for superior stability, and its touchscreen interface offers a menu‑driven layout that ensures simple, intuitive, and convenient operation. The measurement system employs a grating sensor and computer control, with hardness values displayed directly on the LCD screen, making it a mechatronic hardness testing device. It can automatically convert among various hardness scales and determine the minimum specimen thickness. When testing cylindrical specimens, it can automatically apply correction factors. A built-in printer enables easy retrieval of test results. With fully automated operation, it eliminates human error in handling and reading measurements. Additionally, the unit is equipped with an emergency stop feature for enhanced safety.
Main uses and scope of application:
Surface‑hardened steels, copper and aluminum alloy sheets, strip steel, cemented carbides, as well as galvanized, chrome‑plated, and tin‑plated materials—along with various metallic materials undergoing surface heat treatment or chemical surface treatments, and castings and forgings of both planar and cylindrical shapes. These are widely used in the steel, nonferrous metals, automotive, and aerospace industries, as well as in applications involving cemented carbides, ceramics, and stainless steels. Due to its broad range of applicability, Rockwell hardness testing has become extensively adopted in manufacturing, serving as a primary method for assessing product quality and establishing optimal machining processes. The Rockwell hardness tester is a commonly employed instrument in production facilities, colleges and universities, and research institutions for conducting hardness tests and supporting teaching and research activities.
Key functions and features:
1. The 7-inch LCD touch display provides a clear, intuitive visualization of hardness values, converted hardness scales, test methods, test forces, brightness, initial test force hold time, total test force hold time, elastic recovery time, number of measurements, statistical data, test duration, and other key parameters of the testing process.
2. The system features a built-in calibration function that can automatically adjust the error range to 80–120%, or perform separate calibrations for low and high values.
3. When testing curved surfaces, automatic correction is applied based on the standard surface radius.
4. It can store 100 sets of test data, which can be viewed at any time; users can also delete the current data or clear all test data. The main interface displays the average value and the number of measurements. Additionally, a product name can be set.
5. The units of test force can be converted between each other; the conversion units are: (kgf, N).
6. Can simultaneously display: maximum value, minimum value, average value, number of tests, and product name.
7. The main interface can display four conversion scales simultaneously and allows switching between Chinese national standards (GB) and U.S. standards (ASTM).
as well as international (ISO) standards, a total of 20 measurement scales can be converted: HRA, HRB, HRC, HRD, HRE,
HRF, HRG, HRK, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, HK,
HBW, HS, HBS, HV, Rm (tensile strength),
8. You can set the screen timeout; after a prolonged period of inactivity, the screen will automatically enter sleep mode, saving energy and protecting the environment.
9. The upper and lower measurement limits can be set and displayed on the main measurement screen; non‑conforming values trigger automatic alerts.
10. The operating system supports a total of 14 languages, which can be switched at will: Chinese, Traditional Chinese, English, Russian, German, French, Spanish, Portuguese, Turkish, Czech, Japanese, Korean, Thai, and Vietnamese.
11. Equipped with a built-in printer; test data can also be exported via USB to a USB flash drive for storage and analysis.
12. The cast housing features a one-piece, integral structure that remains stable and deformation-free; its pure white automotive baked finish exudes high quality, offers excellent scratch resistance, and retains a like-new shine even after years of use.
13. Our company possesses the capability for independent research, development, design, and manufacturing. We provide lifetime support, including spare parts replacement and maintenance/upgrade services, for our machines.
