FAQs of W405 Water Vapor Permeability Analyzer:
Q: How does the W405 Water Vapor Permeability Analyzer determine water vapor transmission rate?
A: The W405 utilizes the gravimetric (desiccant) method, where water vapor passes through a test sample into a chamber containing desiccant. The precise increase in mass, detected by a high-resolution balance, is used to calculate the water vapor transmission rate.
Q: What types of materials can be tested using the W405 analyzer?
A: This instrument is suitable for assessing films, sheets, laminates, foils, and other packaging materials commonly used in industries such as food, pharmaceuticals, and electronics.
Q: When should the analyzer be calibrated for optimal performance?
A: Calibration is recommended according to laboratory schedules, regulatory requirements, or after major maintenance. Regularly calibrating the humidity sensor and precision balance ensures continued accuracy and compliance with standards.
Q: Where is the W405 ideal for installation?
A: The analyzer is best placed in controlled laboratory environments or quality control labs, operating within ambient temperatures of 5C to 35C and non-condensing humidity up to 85%. Install on a stable surface to accommodate its 65 kg weight and size.
Q: What is the process for running a water vapor permeability test?
A: First, prepare and place the sample in the test cell. Select test parameters via the touch screen, then the W405 automates humidity control and data collection. Measurements can be run independently or in parallel. After completion, results are exported for analysis.
Q: How does simultaneous multi-sample testing benefit users?
A: Running up to three samples at onceeither independently or in parallelsignificantly increases laboratory efficiency, allows comparative analysis, and accelerates product development or quality control workflows.
Q: What are the main advantages of using the W405 analyzer?
A: Key benefits include high sensitivity, intelligent auto-testing, robust data storage and export options, compliance with international standards, and customizable test stations to meet the specific needs of manufacturers, exporters, and suppliers.
