PERMETM　W3/**0 state-of-the-art Water Vapor Transmission Rate(WVTR) Test System innovated by Labthink is a preferred apparatus for evaluating WVTR of films, sheets, foils, membrane and other barrier materials. From automatic testing process feature to automatic temperature and humidity control function, and from interval weighing, auto zero before each weighing characteristics to powerful software, every aspect is considered by our professional designers to minimize operators’ errors and to reach the highest accuracy. Incorporated with 6 independent chambers, PERMETM　W3/**0 mainframe alone can test, with out any influences to each other, 6 specimens at the same time. Considerring customers’ future testing requirements, the PERMETM　W3/**0 has the function of extending satellites:1 master base can connect 9 satellites. That means *0 specimens can be tested simultaneously and independently! Technical Indexes as follows: Test Range: 0.1～*0, **0 g/m2•*4h(Routine) Test Accuracy: 0.*1 g/m2•*4h Resolution: 0.***1 g Test Temperature: *5℃～*5℃(Routine) Temperature Accuracy: �0.1℃ Testing Humidity: *0%RH～*8%RH（Standard *0%RH） Humidity Accuracy: 1%RH Purge Speed: 0.5～2.5 m/s (Optional) Test Area: *3 cm2 Numbers of Specimen: 1 ~ 6 pieces Extension Capacity: 9 satellite modules (***0 specimens) Sample Thickness: ≤3mm ( other thickness is possible by customization)
