Product Description

Product Introduction

WVTR-RC6 Water vapor transmittance testeris a set of industrial, efficient and intelligent WVTR high-end test system, which is suitable for the determination of water vapor transmittance of plastic film, composite film, medical, construction and other materials. Through the determination of water vapor transmittance, the technical index of products such as packaging materials can be achieved.


Product features

Based on the test principle of cup method, it is a water vapor transmittance (WVTR) test system for film samples, which can detect the water vapor transmittance up to 0.1g/m2•24h. disposition 

The high-resolution weighing sensor provides excellent system sensitivity while ensuring high precision.

Wide range, high precision, automatic temperature and humidity control, easy to achieve non-standard testing;

The standard purge speed ensures the constant humidity difference between inside and outside the permeable cup;

The system automatically clears zero before weighing to ensure the accuracy of each weighing;

The system adopts cylinder lifting mechanical junction design and intermittent weighing measurement method, which effectively reduces the system error;

Quick access temperature and humidity verification jack for quick calibration;

Provide two fast calibration methods of standard film and standard weight to ensure the accuracy and versatility of test data;

Precision mechanical design not only ensures the ultra-high precision of the system, but also greatly improves the detection efficiency;

6 permeable cups can be independently tested, the test process interferes with each other, and the test results are independently displayed;

Large size touch screen friendly man-machine effect, easy user operation and fast learning;

Support multi-format storage of test data, convenient data import and export;

Support convenient historical data query, comparison, analysis  and printing and other functions;

Humidity Control Range	Weight Reduction Method: 90%RH~70%RH Weight Gain Method: 10%RH~98%RH (National standard requirement 38°C 90%RH) The definition of humidity refers to the relative humidity on both sides of the film, that is, the weight reduction method is the humidity of the test cup 100%RH- the humidity of the test chamber (10%-30%RH). The weight gain method is the humidity of the test chamber (10%RH~98%RH) - the humidity of the test cup is 0%RH When the temperature is not the same, the humidity range has changed, as follows: (the following humidity customers must provide dry air source, otherwise affect the humidity generation) Temperature 15°C-40°C humidity 10% Rh-98% RH; Temperature 45 ° C Humidity 10%-90%RH Temperature 50°C Humidity 10%-80%RH; Temperature 55 ° C Humidity 10%-70%RH

Test Principle
 

The test principle of permeable cup weighing method is adopted. At a certain temperature, a specific humidity difference is formed on both sides of the sample, and the water vapor enters the dry side through the sample in the permeable cup

The water vapor transmittance and other parameters of the sample can be obtained by the change of the weight of the moisture-permeating cup with time.

 

Conception standards

Applications

Basic  application	Thin film	All kinds of plastic film, plastic composite film, paper plastic composite film, co-extruded film,  aluminized film, aluminum foil composite film, glass fiber aluminum foil paper  composite film and so on.
	Sheets	Water vapor permeability test of various engineering plastics, rubber, building materials and other sheet materials such as PP sheet, PVC sheet, PVDC sheet and so on
	Textile	It is used for testing the water vapor transmittance of textiles, nonwoven fabrics, such as waterproof and breathable fabrics, nonwoven fabrics, nonwoven fabrics for sanitary products, etc.
	Paper, board	It is suitable for water vapor permeability test of paper and board, such as cigarette foil, Tetra Pak sheet, etc.
