As per the above screenshot, during the test the bottles in the #6 and #16 positions leak, the lights of positions #6 and #16 will become green automatically, and system will stop pressurizing the corresponding positions.

Alternatively, the operator can press the position button to stop pressurizing at any point. Leak pressure value and time will be displayed below the button.

The system will also generate a data table for each test to record the test pressure of each position. In the table, positions with a green light will be displayed as “NG” with their respective leakage pressure value. A normal position will be displayed as “OK” with the predefined pressure value. The data table can also be printed out through the mini printer.

SCT-D Stress Crack Tester for PET Bottle Durability

The SCT-D Stress Crack Tester is essential for measuring the stress crack resistance of PET bottles. This device simulates long-term behavior by exposing bottles to sodium hydroxide solution, providing critical data for quality control.

### Multi-Position Testing
Available in models with 6, 12, or 26 testing positions, the SCT-D ensures efficient testing. Each position can be individually controlled, making it versatile for various testing requirements.

### High Accuracy
The tester operates with a testing pressure range of 0-6 Bar and a display resolution of 0.1 Bar. The automated system enhances accuracy and repeatability, with detailed data output for each test.

### Safe and Durable Design
Constructed with high-quality stainless steel and equipped with safety features, including a corrosion-resistant design and anti-explosion observation window, the SCT-D offers a safe testing environment.

Attributes:

• Multi-position design, more convenient and efficient (Please consult AT2E for other position request).
• Automation control ensures high accuracy and repeatability.
• High quality stainless steel frame, which is safe and durable.
• Superior control components ensures accuracy and durability.
• Flexible position selection – each position can be controlled separately by the system. Users can enable the positions (from 1 to 26) according to their testing requirements.
• Automatic pressure compensation during the test process.
• Suitable for testing various sizes of bottle.
• Corrosion-resistant design
• Anti-explosion and clear observation window, which allows a safe and easy way of observing sample status during a test.
