Sistem Uji Tingkat Transmisi Uap Air C360H, dirancang dan diproduksi berdasarkan metode penentuan gravimetri dan sesuai dengan persyaratan ASTM E96. Instrumen ini dapat digunakan untuk mengukur tingkat transmisi uap air dari bahan penghalang dengan sifat penghalang kelembaban tinggi, sedang dan rendah dengan rentang pengujian yang luas dan efisiensi pengujian yang tinggi. Instrumen ini menampilkan desain ruang tes yang dipatenkan Labthink dengan beragam hidangan uji. C360H dilengkapi dengan piringan uji yang dibuat secara presisi, keseimbangan yang sangat akurat, peranti lunak profesional tertanam yang mendukung pengontrolan otomatis suhu, kelembaban, dan laju aliran secara tepat serta menjamin sensitivitas pengujian dan pengulangan hasil pengujian. C360H berlaku untuk penentuan permeabilitas uap air film plastik, terpal, kertas, paket dan bahan kemasan lainnya dalam makanan, farmasi, peralatan medis, bahan bangunan dan barang konsumen, dll.
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.
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.
