FAQs of NAC432W3/031 Water Vapor Transmission Rate Tester:
Q: How does the NAC432W3/031 determine water vapor transmission rate in packaging materials?
A: The tester uses the gravimetric (cup) method, which involves monitoring weight changes as water vapor passes through a sample. By controlling humidity and temperature precisely, it accurately calculates the transmission rate, making it suitable for evaluating moisture barriers.
Q: What types of materials can be tested with this equipment?
A: The NAC432W3/031 is ideal for assessing food packaging, medical packaging, and various barrier films. Its versatile configuration also allows for application with diverse packaging substrates that require water vapor transmission rate assessment.
Q: When is calibration required and how is it performed?
A: Calibration ensures measurement accuracy and should be performed periodically or when results deviate unexpectedly. The device supports standard weight calibration, which can be executed according to laboratory schedules or quality control requirements.
Q: Where can the test data be stored or exported from the NAC432W3/031?
A: Test data can be easily exported to external devices via USB or sent directly to a connected printer. This provides flexibility for data management, reporting, and long-term record keeping in laboratory or industrial settings.
Q: What is the testing process for multiple samples?
A: Up to three samples can be tested simultaneously, each in an independent chamber with adjustable humidity and gas supply. Operators place samples according to instructions, set conditions via the touch screen, and monitor real-time data throughout the automatic testing cycle.
Q: How does the equipment ensure user safety and reliability during operation?
A: The tester is equipped with over-load and over-temperature protection. Its corrosion-resistant build and automated control systems minimize risks, while accurate sensors monitor conditions, ensuring safe and reliable operation for users in laboratory environments.
Q: What benefits does automating water vapor transmission testing provide?
A: Automation streamlines the workflow, reduces operator variability, and enhances data reliability. With features like multi-channel testing, touch control, and real-time monitoring, the tester ensures more consistent, efficient, and reproducible test results.
