Water Vapor Permeability Analyzer

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:
Both weigh gain and weight loss method. 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:

1. Automatic test: just need to 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;
2. Computer software in full compliance with GMP "computerized system" requirements, with user management, rights management, data audit tracking and other functions.
3. Process monitoring, real-time recording, the entire testing process to reproduce; curve powerful graphics capabilities, ease of comparison testing, analysis;
4. Computer software uses encryption common database system, data can be exported, and has data storage, query, print, and other functions. Through the analysis of historical data, easy to grasp the historical dynamic products.
5. Power-off saving function; full monitoring and automatic recording; sampling rate is adjustable;
6. Humidifier automatic replenishment, water once, a month continuous test

Features:

1. Along with weight loss and weight gain methods
2. Independent data of each cavity；
3. The world's top high-precision sensors (MT / Mettle - Toledo), test data is accurate, test time is short
4. Pure semiconductor temperature control, no electric wire, automatic temperature control in cooling heating, temperature control is more accurate; parallel work, higher reliability;
5. Patented technology constant intermediate temperature balance: Balance temperature, the balance within the school, to exclude the interference of environmental change, weighing more accurate;
6. Patented mist humidifier, high precision humidity control
7. Desiccant Free Replacement: automatic regeneration of the drying gas occurs, the desiccant needs not to be replaced;
8. 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;
9. Before sample weighing, stop the wind, gas, clear the balance to ensure accurate weighing
10. Sample disk patented lifting and rotating mechanism, sample switching more stable;
11. Patent balance protection agency, perfect test case insulation structure, double glass temperature door (with temperature control), and anti-fog, anti-condensation
12. Patent no slide specimen cup, does not generate any distortion or damage to specimen
13. Embedded control, PC machine full process monitoring, intelligent testing process
