Description
Product Introduction:
The PCHBS‑3000 digital Brinell hardness tester allows you to perform measurements effortlessly using just a single touch‑screen tablet. All required test parameters can be directly selected, adjusted, and analyzed on the device. By connecting to a CCD imaging and data‑acquisition system, the tester displays clear, real‑time images of the indentation on the PC, enables automatic locking of the indentation for precise hardness measurement, and automatically saves test data while generating comprehensive reports. Operation is simple and rapid, effectively eliminating human‑induced measurement errors. Powered by a tablet platform, the system supports expanded functionality via internet connectivity and can be connected to external monitors, printers, and other peripherals. The instrument’s software employs intelligent computer programming and photoelectric sensing technology. Users can independently set test conditions, with the 5.6‑inch multi‑function touchscreen displaying the testing method, upper and lower limits, measured indentation length, hardness values, conversion factors, test force, dwell time, and number of measurements. It also allows users to enter the year, month, and date, view test results, and manage data processing. Measurement data can be printed via the built‑in printer or transmitted to a computer through a data interface. The optical system utilizes high‑magnification LED illumination, delivering crisp, high‑contrast images with adjustable brightness to reduce operator fatigue during extended use. The hardware incorporates advanced electronic sensor‑based loading technology, featuring a closed‑loop control system in which the CPU manages sensor signal acquisition, while a stepper motor automatically applies and releases the test force and provides automatic force compensation, ensuring greater accuracy and stable readings. An emergency stop mechanism is also included, meeting EU CE safety standards. With its user‑friendly design, the system offers enhanced reliability and stability.
Main uses and scope of application:
1. Suitable for hardness testing of metallic materials with coarse grains, it can reflect the material’s overall performance.
2. Cast iron, steel, and nonferrous metals, particularly softer metals such as pure aluminum, lead, and tin.
3. It can be used for hardness testing of certain non-metallic materials, such as rigid plastics and bakelite.
Main functions and features of the hardness tester:
1. This instrument features high accuracy, excellent repeatability and stability, simple operation, practical convenience, and outstanding cost-effectiveness.
2. Equipped with a 11-level test force, it can accommodate a wider testing range;
3. Equipped with a digital micrometer eyepiece and a precise data‑processing system, it can display the hardness value directly with a single click.
4. The system features a built-in calibration function, allowing manual adjustment of the input calibration instrument and also enabling calibration of the eyepiece magnification.
5. Optical system brightness adjustment range: 0–100
6. Can store up to 100 sets of test data.
7. The operating system supports switching between Chinese and English.
8. The main interface can display five conversion scales simultaneously.
9. Equipped with a built-in printer for outputting measurement data, or networked to a computer to transmit the host’s measurement data for editing and storage;
10. Equipped with a high-performance stepper motor for automatic application and removal of test force, resulting in reduced noise during testing.
11. Utilizing photoelectric sensing technology and a microcomputer control system, automatic compensation is achieved, ensuring precise and stable test results.
12. Automatically inputs the indentation diameter and directly displays the hardness value; it supports dual display of any hardness unit, eliminating the tediousness of table lookups.
13. Built-in high-magnification LED optical measurement system, offering high image clarity and adjustable brightness to reduce operator fatigue during extended use.
14. The housing is cast in a single piece, ensuring structural stability and resistance to deformation, enabling operation under relatively harsh environmental conditions.
15. The surface is finished with automotive baking‑paint technology, offering excellent resistance to scratches and maintaining a bright, like‑new appearance even after years of use.
Functions and features of the automatic measurement system:
1. Application: Used for measuring Brinell hardness indentations.
2. Test force range: 62.5, 100, 125, 187.5, 250, 500, 750, 1000, 1500, 3000 kgf
3. Indentation measurement accuracy: ±0.5%
4. Automatically measures indentation and calculates Brinell hardness values in accordance with ASTM E10.
5. German Industrial Standard DIN 1605 automatically measures the indentation of test specimens and standard blocks, and calculates the impact‑type Brinell hardness value HB2.
6. Automatic Measurement: Automatically or manually capture the indentation, measure its diameter, and calculate the corresponding Brinell hardness value.
7. Hardness Value Conversion and Validity Verification: The system can convert the measured Brinell hardness value HB into other hardness values, such as HV, HR, and others.
8. Data Statistics: The system automatically calculates and stores statistical values such as the average hardness and variance of the measured readings.
9. Over‑limit alarm: Automatically flags abnormal values; when the hardness exceeds the specified threshold, an automatic alarm is triggered.
10. Test Reports: Automatically generate reports in Word or Excel format, with customizable report templates.
11. Data Storage: Measurement data, including indentation images and other relevant information, can be stored as documents.
12. Other Functions: Includes all functions of the image processing and measurement system, such as image acquisition, calibration, image processing, and geometric dimension measurement.
Quantity, document annotation, album management, and fixed‑ratio printing, among others;
13. Ease of use: With a single click on the interface button, the indentation measurement is performed automatically; if manual measurement or result modification is required, you can proceed directly.
Simply drag the measurement box;
14. Strong noise resistance: Advanced and reliable image recognition technology can accurately identify indentations on complex sample surfaces, with two automatic measurement modes available.
Handle extreme cases;
