Full Description

C360H Water Vapor Transmission Rate Test System, is designed and manufactured based on the gravimetric determination method and conforms to the requirements of ASTM E96. This instrument can be used to measure the water vapor transmission rate of barrier materials with high, medium and lower moisture barrier properties with a wide testing range and high testing efficiency. The instrument features Labthink’s patented test chamber design with multiple test dishes. C360H is equipped with precision made test dishes, highly accurate balance, embedded professional software which supports automatic controlling of temperature, humidity and flow rate precisely and guarantees the testing sensitivity and repeatability of the test results. C360H is applicable to determination of water vapor permeability of plastic films, sheeting, paper, packages and other packaging materials in food, pharmaceutical, medical apparatus, building materials and consumer goods, etc.

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.
