AMETEK MOCON Launches AQUATRAN Model 3 Water Vapor Measurement Instrument for Ultra High Barrier Structures

AMETEK MOCON, a leading 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 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, such as televisions and photovoltaics for solar panels, are growing exponentially. 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, with its easy-to-use interface, puts the testing capability into the hands of a wider user base,” explains Ryan Holland, product manager, AMETEK MOCON.

The AQUATRAN Model 3 measures each molecule of water vapor that passes through the sensor, and requires no calibration. The response is linear throughout the entire measurable range of the sensor, so measurements of ultra barrier materials are guaranteed to be highly accurate and repeatable.

The instrument is ideally suited to test components used in televisions, phones, virtual reality appliances, as well as other products using this latest technology. Products using photovoltaic technology, such as solar panels, also can benefit from the AQUATRAN’s measurement sensitivity.
