AMETEK MOCON, a global provider of instruments and services for testing, measuring and analyzing invisible gases, has launched a new system to measure the water vapor transmission rate (WVTR) of ultra-high barrier packaging films and materials.
The next-generation AQUATRAN® Model 3 WVTR measurement instrument targets ultra-high barrier materials that are engineered to push the performance envelope. These include flexible films for organic light-emitting diode (OLED) displays, solar panels and similar demanding applications, which require accurate and extremely sensitive instrumentation to confirm performance attributes.
The use of OLEDs for consumer electronics is growing, however, the electronic components within OLED displays are extremely sensitive to water vapor. The slightest exposure to humidity can cause a series of problems that significantly decrease a product’s usable life. The AQUATRAN Model 3 offers an easy-to-use interface, and puts the testing capability into the hands of a wider user base.
The AQUATRAN Model 3 measures each molecule of water vapor that passes through the sensor, requiring no calibration. The response is linear throughout the entire measurable range of the sensor, so measurements of ultra-barrier materials are guaranteed to be accurate and repeatable.
