Product Features
A brand-new external independent controller
adding an independent external manual control unit provides a completely new solution for the measurement, control, and operation of the testing machine. USB data transmission fully supports laptops, tablets, and desktop computers; it is an important part of leading the development of testing machine technology.
Multi-functional handheld controller
controls the raising and lowering of the loading cylinder and also features a one-button testing function, making the testing process more convenient.
3.U-shaped body
the body is made of QT500-7 material in a single casting, resulting in better frame rigidity, higher strength, and better stability.
Equipment Operation Monitoring System
Our company has made revolutionary improvements to the original high-voltage circuits, adding phase sequence and phase loss self-test indication functions, as well as electrical overcurrent and overload protection functions, making the equipment operation safe and reliable.
Pressure monitoring instrument
Real-time display of differential pressure start-up pressure, system pressure, and clamping pressure of the servo oil source, ensuring the normal operation of the equipment.
Universal Testing Machine Control Software
The universal testing machine control software adopts DSP technology and a neuron adaptive control algorithm to achieve multiple closed-loop control modes such as constant rate test force, constant rate cylinder displacement, and constant rate strain. The control modes can be arbitrarily combined and smoothly switched. It has a network interface, enabling data networking and remote control functions.

General FAQs
What is a concrete Compression testing machine?
A concrete compression testing machine is a specialized device designed to measure the compressive strength of concrete specimens (e.g., cubes, cylinders). It applies controlled axial pressure to the specimen until failure, providing critical data for assessing concrete quality in construction, infrastructure, and material testing applications.
How does a concrete Compression testing machine work?
The machine operates by placing a concrete specimen (typically 150mm cubes or cylinders) between two rigid platens. A hydraulic or servo-electric system applies a gradually increasing load to the specimen. Load cells and sensors monitor the force applied, while integrated software records the maximum load at failure. This data is used to calculate compressive strength (force divided by cross-sectional area).
What key technical specifications should I consider when selecting a machine?
Critical specifications include:
- Maximum test force: Ranges from 300kN to 5000kN
- Loading rate accuracy: Complies with standards (e.g., 0.2–0.5 MPa/s per ASTM C39).
- Platen size: Must accommodate specimen dimensions (e.g., 150mm cubes require ≥180mm platens).
- Control system: Manual, semi-automatic, or fully automatic (with software for data logging/reporting).
Accuracy class: Typically Class 1 (±1% of indicated load) for precise results.
Is the machine compliant with international standards?
Yes. Our concrete Compression testing machines meet global standards, including:
- ASTM C39 (USA): Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens.
- EN 12390-3 (EU): Testing Hardened Concrete—Part 3: Compressive Strength of Test Specimens.
- GB/T 50081 (China): Standard for Test Methods of Mechanical Properties on Ordinary Concrete.
- ISO 4012: Concrete—Compressive Strength of Test Specimens.
How do I ensure safe operation?
Follow these safety guidelines:
- Always wear PPE (safety glasses, gloves, steel-toe boots).
- Secure specimens firmly to prevent slipping during testing.
- Avoid overloading beyond the machine’s maximum capacity.
- Regularly inspect hydraulic lines, platens, and safety guards for damage.
- Train operators on emergency stop procedures.
What maintenance is required?
Routine maintenance includes:
- Daily: Clean platens and remove debris; check oil levels (hydraulic models).
- Weekly: Inspect hydraulic hoses for leaks; lubricate moving parts.
- Quarterly: Calibrate load cells (per ISO 7500-1 or ASTM E4 standards).
- Annually: Professional inspection of hydraulic/servo systems and software updates.
How do I choose the right machine capacity?
Select capacity based on expected concrete strength and specimen size:
- For low-strength concrete (C15–C30): 2000kN machines suffice.
- For high-strength concrete (C50–C80) or large specimens (e.g., 200mm cylinders): 3000kN or higher is recommended.
- Consult our technical team for custom capacity recommendations.
What after-sales support do you offer?
We provide comprehensive support, including:
- On-site installation and operator training.
- 12-month warranty on parts and labor.
- Calibration services (ISO 17025 accredited).
Fast spare parts delivery and technical troubleshooting via phone/email.
Can the machine integrate with data management software?
Yes. Our advanced models include software for:
- Real-time load-displacement graphs.
- Automated report generation (PDF/Excel).
- Data storage and compliance with quality management systems (e.g., ISO 9001).
What factors affect test result accuracy?
Key factors include:
- Specimen preparation: Proper curing, flat/parallel ends, and no cracks.
- Loading rate: Deviations from standard rates (e.g., too fast) can overestimate strength.
- Machine calibration: Outdated calibration leads to inaccurate load readings.
- Environmental conditions: Temperature/humidity variations (test in controlled labs, 20±2°C).
