Product Features

It is suitable for the determination of water vapor permeability of various materials such as plastic films, composite films, fabrics, leather, solar cells, building materials, and other materials in the fields of food, hygiene, medical, textile, and leather.

 

working principle

Weighing method. Control the temperature and humidity of the test environment. A fixed humidity difference is formed on both sides of the sample. Water vapor penetrates the sample and enters the dry side. The amount of change of the weight of the sample cup with time is measured, and the moisture permeability and moisture permeability coefficient of the sample are analyzed.

 

Application characteristics

Ÿ Fully automatic test: only need to set the temperature, humidity, warm-up time and stop conditions, the test will be carried out automatically after the start, automatically judge the end of the test and save the test results;

Ÿ Power-off preservation function; full monitoring and automatic recording; adjustable sampling rate;

Ÿ The test process can be reproduced throughout; the powerful graphic curve function is convenient for comparative testing and analysis;

Ÿ The host software has a general database system, data can be exported, and data storage, query, printing, etc. can be performed. Through the analysis of historical data, it is easy to grasp the historical dynamics of the product.

 

Features

Ÿ Weighing principle: It can be increased by weight or reduced by weight. It fully complies with national standards, and the penetration environment is consistent with the weighing environment, eliminating operation errors

Ÿ Dual test mode: interval weighing, continuous weighing

Ÿ The world's top high-precision sensor (MT/METTLER TOLEDO), accurate test data, short test time

Ÿ Pure semiconductor temperature control, no heating wire, automatic temperature control, temperature control is more accurate; parallel operation, higher reliability;

Ÿ Internal environment control of the test chamber: double plane circulating wind, automatic wind speed control

Ÿ Before weighing the sample, stop the wind, stop the gas, and clear the balance to ensure accurate weighing

Ÿ High-precision humidity control, a variety of humidity control methods (drying tray, drying air tower, humidifier)

Ÿ The patented non-slip sample cup does not cause any distortion or damage to the sample

Ÿ Embedded control, PC monitoring throughout the process, intelligent test process
