The OPT-5000 Oxygen Permeability Tester features automated temperature control and single- or dual-side relative humidity control to easily accommodate a broad range of laboratory and production appliances. Touchscreen-operated tester also uses specially designed test sample holders to eliminate the need for grease or other lubricants. Accuracy and broad testing range for water vapor permeability on the L80-5000 extends from 0.03 to 10ꯠ g/m2 per day. Unlike other testers that measure extractive values, the LYSSY provides a very sensitive and reliable humidity sensor with a large linear, dynamic range that measures samples directly within the test chamber.
