C301B Water Vapor Permeability Test System

Product catalog summary

Overview: The C301B Water Vapor Transmission Rate Test System is designed to measure the water vapor transmission rate of barrier materials using an infrared sensor method. It complies with ASTM F1249 and ISO 15106-2 standards, making it suitable for testing materials in various industries such as food, pharmaceuticals, and electronics.

Features:

Equipped with a patented infrared sensor with a long service life.
Supports temperature control for diverse testing conditions.
Features a stainless steel test cell for enhanced sealing performance.
Includes a manual isolation valve and flow regulator to reduce failure rates.
Compact design with fast cooling capabilities.
Provides reference film for quick calibration.
Operates independently with single-chip microcomputer control.
Exports test reports in formats like EXCEL and PDF.
Optional micro printer for automatic data printing.
RS232 data interface for computer connectivity and data analysis.

Test Principle: The system uses a pre-conditioned specimen clamped in a test cell. Nitrogen with stable humidity flows on one side, while dry nitrogen flows on the other. The humidity difference causes water vapor to permeate through the specimen, which is then measured by the infrared sensor to calculate the transmission rate.

Standards: The system adheres to ASTM F1249, ISO 15106-2, GB/T 26253, JIS K7129, and YBB00092003-2015 standards.

Applications: Suitable for testing water vapor transmission rates in various films, sheets, and packaging materials, including plastic films, aluminum foils, and silicon wafers.

Technical Specifications:

Test range: 0.1 to 40 g/(m2·day).
Resolution: 0.1 g/(m2·day).
Test temperature: 15 to 50°C with a resolution of 0.1°C.
Humidity range: 4%RH to 100%RH ±2%.
Specimen size: 3.8” x 3.8” (9.7cm x 9.7cm).
Specimen thickness: ≤120 Mil (3mm).
Gas pressure: 7.2 PSI / 50 kPa.
Instrument dimensions: 12.9” H x 16.9” W x 15.7” D.
Power supply: 120VAC±10% 60Hz / 220VAC±10% 50Hz.
Net weight: 50 lbs (23 kg).

Product Configuration: The standard configuration includes the instrument mainframe, temperature control device, porous ceramic plate, sampler, and vacuum grease. Optional parts include professional software, GMP computer system requirements, and a micro-printer.

Notes: The product specifications are subject to change, and different humidity levels can be achieved using saturated salt solutions as per ASTM E 104.
