 Product Features 
 New Generation Test  Chamber and Test Dishes
  Patented  test chamber and test dishes with advanced hydrodynamic and thermodynamic  designs ensure the uniform flow rate over the specimen surface, stable  temperature and humidity, creating a uniform and stable testing environment. As  a result, the test duration is shortened and the test results will be more  accurate. 
 Excellent Testing  Abilities of High and Low Barrier Materials
  The  testing conditions will be regulated precisely in real time, which ensures the  high testing accuracy and repeatability of high and low barrier materials. 
 Automatic Controlling of  Temperature, Humidity and Air Velocity
  Labthink’s  proprietary thermostat technology ensures that the test chamber is precisely  temperature controlled and remains stable throughout the test. 
  Air  velocity is monitored and regulated in real time.
  High-efficiency  and mist-free automatic humidity regulator meets the requirements for long-term  continuous tests.
  It is  unnecessary to replace the inner core of the desiccator, which can continuously  work for 20,000 hours. 
 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 DataShieldTM system facilitates 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 test dish which contains water or desiccant inside. The test dish is placed in the test chamber with stable temperature, humidity and air flow. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the test dish periodically, water vapor transmission rate and other parameters can be obtained.
