The Minneapolis company, which specialises in permeation testing instruments and laboratory services for product sectors including packaging, says the Aquatran Model 2 targets commercial or developmental ultra-high barrier structures including flexible films.
It uses proprietary technology to “accurately and repeatably” measure WVTR down to 5x10-5 g/(m2-day) – one order of magnitude lower than its predecessor Model 1, which was launched in 2005.
"The Aquatran Model 2 utilises Mocon’s newest AquaTrace Gold coulometric longer-life sensor, which is based on Faraday’s Law,” the company says.
“Every water molecule entering the sensor is directly converted to a measureable charge. No calibration is necessary, assuring an accurate test result.”
The Aquatran Model 2 is available in two versions: the G system operates between 35-90% relative humidity (RH) and a temperature range of 10-40°C; the W version offers 100% RH and a temperature range 10-50°C. Customers with existing Aquatran Model 1 Master units can upgrade their systems by attaching Model 2 satellites to the Model 1 master.
