C390h Water Vapor Permeation Analyzer, Water Vapor Permeability Tester

Product Features

Patented Sensor Technology
The instrument uses Labthink's proprietary infrared sensor for water vapor analysis, which has excellent precision, repeatability and service life. Higher sensitivity and stability make it unnecessary to calibrate with distinct reference films for different test ranges and the interval between calibrations is extended. The test range of the sensor can be set automatically according to the transmission rate of the specimens without manual adjustment.

New Generation Integrated Testing Block
The patented three-cell integrated test block structure using advanced thermodynamics and hydrodynamics analysis greatly improves the temperature, humidity and flow measurement accuracy across the three test cells and supports sequential testing of three samples.

Automatic Control of Temperature, Humidity and Flow Rate
The internal temperature and humidity of the instrument are automatically adjusted with temperature and humidity sensors, maintaining the stability of the test specimen environment. Automatic flow rate control ensures constant flow during the testing process and minimizes any errors caused by an unstable flow rate.

Easy-to-use and High-efficiency System
The automatic test mode, combined with the instrument features, eliminates the need for manual adjustments to quickly obtain accurate results, saving training costs and releasing staff from manual monitoring so that they are available for other tasks.
The professional test mode provides flexible and rich instrument control functions to meet individual scientific research needs.
Unique, optional DataShield^TM system, meets the requirements for centralized management of user data. It supports a variety of formats of exported data. Reliable security algorithms are used to prevent data leakage. It supports universal wired and wireless LAN, optional private wireless network and third-party software.

User-oriented Service Concept
Adhering to our user-oriented service concept, Labthink has created a customization system that provides flexible and comprehensive customization services for the accommodation of non-standard specimens and packages.

Test Principle

The test specimen is mounted in the diffusion cell, which is divided into a dry chamber and a controlled-humidity chamber. The dry side of the specimen is swept by a flow of dry nitrogen, and the water vapor permeating through the specimen from the controlled-humidity chamber is carried by dry nitrogen to the infrared sensor where proportional electrical signals will be generated. The water vapor transmission rate is obtained by analyzing and calculating the electrical signals. For whole package specimens, the dry nitrogen flows inside the specimen while the outside of specimen is maintained in a high humidity environment.
