Description
Product Introduction:
The CHRTS‑150S touchscreen digital dual Rockwell hardness tester series is a next‑generation, high‑tech intelligent instrument. It features a closed‑loop loading control system, delivering high test force accuracy and excellent repeatability and stability of readings. The housing is integrally cast and finished with an automotive‑grade baked paint process, boasting a modern design and ensuring outstanding reliability, ease of operation, and reproducibility, while offering comprehensive functionality and clear, intuitive display. With automatic application and removal of test force, it supports hardness testing across the full range of Rockwell scales. The measuring unit employs a grating sensor, with hardness values displayed directly on the LCD screen, and enables automatic conversion among various hardness parameters. When testing cylindrical specimens, it can automatically apply correction factors. A built-in printer allows for easy retrieval of test results. This device achieves fully automated operation, eliminating human error in handling and reading measurements. Additionally, it is equipped with an emergency stop mechanism.
Main uses and scope of application:
Surface‑hardened steels, copper and aluminum alloy sheets, strip steel, cemented carbides, as well as galvanized, chromium‑plated, and tin‑plated materials—along with various metallic materials undergoing surface heat treatment or chemical surface treatments—are all suitable for testing. This includes castings and forgings, as well as flat and cylindrical workpieces. Applications span the steel, nonferrous metals, automotive, and aerospace industries; additionally, it is used for cemented carbides, ceramics, and stainless steels. Due to its broad range of applicability, Rockwell hardness testing has become widely adopted in manufacturing, serving as a key method for quality inspection and for determining optimal machining processes. The Rockwell hardness tester is a commonly used 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 8-inch LCD touch display provides a clear, intuitive view of the hardness value, converted hardness, test method, test force, brightness, initial test force holding time, total test force holding time, elastic recovery time, number of measurements, statistical data, test duration, and other parameters.
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, allowing you to view the data at any time, as well as delete the current data or clear all test data.
5. The units of test force can be converted between each other; the conversion units are: (kgf, N).
6. Can simultaneously display: average value, number of tests, and product name.
7. The main interface can simultaneously display four conversion scales and allows switching among the following standards: Chinese National Standard (GB), American Standard (ASTM), and International Standard (ISO). A total of 20 measurement scales can be converted, including HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRK, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, HK, HBW, HS, HBS, HV, and 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 an automatic alarm.
10. The operating system supports 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 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 to independently research, design, and manufacture products. We provide lifetime support for spare parts replacement and maintenance upgrades.
