Permatran-W® Model 1/50 moisture vapor transmission rate analyzer is between 30- and 70-percent less expensive than other units available, the co. says. The system is a single-cell, standalone instrument, designed to test medium-to-low barrier films within the range of 0.1-1000-gm/m²/ day and less than 65-mL thick. Two factors, temperature and relative humidity (RH), are what impact permeation. The MVTR analyzer has been engineered to quickly and automatically generate relative humidity, and it also has a small footprint and does not require an additional computer because the software is built into the unit. The operator uses a keypad to input the test parameters (displayed on an easy-to-read screen). Parameters can be saved in a QuickStart menu, which enables fast startup the next time the material is tested. Is suitable as an entry-level WVTR analyzer for food, beverage, pharmaceutical, building material and electronic applications, the co. states. This instrument also conforms to ASTM 398 and TAPPI 523 standards.
