The GBPI model W330 has three test chambers with three separate sensors, and is a self standing instrument. W330 gives simultaneous test reports, as all the test chambers have separate SENSOR. It measures trace water vapor transmission rates in packaging barrier films. Model W330 ensures the high precision of the testing results with its accurate electromagnetic balance type weighing cell and the circuit handling. It can precisely control the temperature and simulate the humidity. The dual-testing mode (increasing and decreasing weight methods) is initially adopted. Testing curve could spontaneously show the permeation, temperature, humidity and the weight of water permeating cup. It also features auto-judging, auto-outage, and auto-storage of the datau2019s. The adopted TCP/IP interface make it easy to inspect the running state, controlled by computer through USB. It is designed and manufactured according to the standard ISO2528:1995、GB/T1037-1988 、GB/T16928-1997 、YBB00092003、ASTM F1770、ASTM D1653-03 、ASTM E96-00e1, ASTM E-398, TAPPI T464.
1. Automatically control, three samples can be tested independently or with combination form, each chamber can be set different temperatures, and tested different samples
2.The mainframe through the USB port connect to computer, or without connecting computer , you can use the true color touch screen to work independently; 3, The sample can be tested by single chamber,or double chambers or three chambers .
controlling methods of electromagnetic technology , excellent structure and accuracy temperature; 5, The unique design of dehumidification chamber, using the reference flow ratio method to control humidity, excellent performance of controlling wet; 6, Simple operation, prevention function for parameter setting errors; 7,The curves of each chamberu2019s temperature, humidity, weight, and transmission display indepently,continous to display four groups curve,can monitor the interaction of parameters.
8, The software interface supports dynamic display of data; 9, The software interface supports the dynamic scaling curve; 10, The software displays status of each curve in time; 11, With data storage capabilities to facilitate the analysis of experimental results; 12, Optional pairs of air humidity controlling devices, more precise of controlling wet;
13, Optional weight method, to achieve double test method;
