Vapor Permeability Tester

Product Features:

For plastic films, laminated films, fabrics, leather, solar cells, building materials and other materials, as well as the vapor permeability test of tableware, health, medical, textile and leather, and other fields of materials.

Determination of vapor transmission rate, quality of control materials, and provide accurate technical parameters of product quality inspection and control. Films, bottles and bags can be measurable.

Working Principle:

Weigh method. Control test environment temperature, humidity, wind speed, fixed humidity difference form on two sides of samples. vapor goes through the sample into the dry side. Lift permeable cup using air cylinder mechanism, weigh permeable cup in even space. Measure the weight of sample cup according to decreased amount of time, and analyze the vapor permeability and vapor permeability coefficient.

Application Characteristics:

Automatic test: just set the temperature, humidity, and warm-up time and stop conditions, after that, test begins automatically; automatically determine the end of the trial and save the test results;

Power-off saving function; full monitoring and automatic recording; sampling rate is adjustable;

The entire testing process can reproduce; powerful graphics curve function, easy comparative testing, and analysis;

Host software has a common database system, and data can be exported, for data storage, query, print, and other functions. Through the analysis of historical data, it’s easy to grasp the product historical dynamic.

Features:

1. Independent data of each cavity；

2. The world's top high-precision sensors (MT / Mettle - Toledo), test data is accurate, test time is short

3. Pure semiconductor temperature control, no electric wire, automatic temperature control in cooling heating, temperature control is more accurate; parallel work, higher reliability;

4. The patented technology of constant temperature balance: balance temperature, eliminate the interference of environmental change, weighing is more accurate;

5. Desiccant Free Replacement: automatic regeneration of the drying gas occurs, the desiccant needs not to be replaced;

6. Strict speed control: double spiral loop wind, wind speed measurement, in full compliance with standards, inside testing temperature field and humidity field are more uniform;

7. Before sample weighing, stop the wind, gas, clear the balance to ensure accurate weighing

8. Sample disk patented lifting and rotating mechanism, sample switching more stable;

9. Patent no slide specimen cup, does not generate any distortion or damage to specimen,

10. Embedded control, PC machine full process monitoring, intelligent testing process

Standards compliant
