| Features: The GBPI model W303 water vapor transmission rate tester has three test chambers with three separate sensors, and is a self standing instrument. It measures trace water vapor transmission rates in packaging barrier films. It 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. 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 . 4.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 chamber’s 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; |
