Two-Chamber Water Vapor Transmission Rate Tester with Computer Software

DESCRIPTION / TECHNICAL SPECIFICATIONS

This is a Water Vapor Permeability Analyzer, a high-precision testing system for measuring the Water Vapor Transmission Rate (WVTR) of various packaging films and barrier materials. This instrument fully complies with the requirements of dozens of leading international standards, including ASTM E96, ISO 2528, and TAPPI T464, making it a vital tool for quality control in the food, pharmaceutical, and electronics industries. The following are its detailed technical specifications and capabilities.

The instrument operates using the highly accurate gravimetric method, equipped with a high-resolution 0.0001g electromagnetic balance weighing cell from a leading European brand. Its key advantage is the dual test chamber design, where each chamber has a separate sensor, allowing for the simultaneous and independent testing of two samples to maximize laboratory productivity. With an extremely wide measuring range from 0.02 to 10000 g/m²·24h and a testing precision of 0.001g/m²·24h, it can test everything from high-barrier to low-barrier materials.

This system offers extremely accurate and stable control of the test environment conditions. The testing temperature range is adjustable from 10°C to 50°C with a control precision of ±0.1°C, while the humidity range is adjustable from 0% to 90% RH with a precision of ±2%RH. The testing process is fully automatic, from parameter locking and auto-judging to auto-storage of data, which significantly reduces operator workload and ensures result consistency.

Operational flexibility is key to this system's design. The instrument can function as a standalone unit operated via its color touch screen, or it can be connected to a computer via a USB port for expanded functionality. When connected, the advanced software provides a visual interface with real-time dynamic curve display, extensive data storage for historical analysis, and the ability to easily export data for reporting and printing purposes, making it a complete and versatile WVTR testing solution.
