Attributes:

• Muilt-position design, more convenient and efficient
• 2 test modes: “SP” & ”PS” mode :
  • “SP” mode: the system auto fills the samples with water and fill the vessels with solution, then lifting units descend to the predefined distance and then pressurize the samples according to the CYCLE setting.
  • “PS” mode: the system auto fills the samples with water and fill the vessels with solution, then pressurize the sample first and hold for the preset time, then the lifting units descend to the predefined distance and keep pressuring the sample according to the CYCLE setting
• PLC control ensures the high accuracy and reliability
• High quality stainless steel frame, more safe and durable
• Flexible position selection, each position can be controlled separately by system. Users can enable the positions according to their test requests.
• Automatic affusion system
• Auto pressure compensation during test process
• Suitable for testing various bottle size
• Corrosion-resistant design
• Anti-explosion and clear observation window, safe and easy to observe the sample status during tests
• Various safety design

FAQ for SCT-PLC High Accuracy Stress Crack Tester

What is the SCT-PLC Stress Crack Tester used for?

The SCT-PLC Stress Crack Tester is designed to measure the stress crack resistance of blow-molded PET carbonated soft drink bottles. It evaluates the propensity for base cracking when exposed to an aqueous sodium hydroxide solution, providing insights into the long-term durability of the bottles.

How does the SCT-PLC ensure accurate testing results?

The SCT-PLC utilizes PLC control technology, which guarantees high accuracy and repeatability in testing. It features an automatic affusion system and allows for precise control of testing conditions, including pressure and timing, ensuring reliable results.

What are the testing modes available in the SCT-PLC?

The SCT-PLC offers two testing modes: “SP” mode, where the system auto-fills samples and then pressurizes them according to a set cycle; and “PS” mode, where samples are first pressurized and held for a preset time before being subjected to further testing. This flexibility allows for various testing scenarios based on user requirements.

What are the technical specifications of the SCT-PLC?

The SCT-PLC can test samples with diameters ranging from 60 to 120 mm and heights from 150 to 350 mm. It operates under selectable pressures from 0 to 6 Bar and has a testing time that can be adjusted from 0 to 200 minutes. The device features a 7” LCD touch screen for easy operation and monitoring.

Is the SCT-PLC suitable for different bottle sizes?

Yes, the SCT-PLC is designed to accommodate various bottle sizes, making it versatile for testing different PET bottle formats. Users can select positions and control each one separately according to their specific testing needs.

What optional accessories are available for the SCT-PLC?

Optional accessories for the SCT-PLC include a mini printer for printing test results and “QualiCrack” professional software for enhanced data analysis and reporting capabilities.
