Water Vapour Permeability Tester Easy and reliable testing for water vapour permeability Simplicity in operation due to the high degree of automation - the quality of tests performed is less operator dependent Easy to use operator interface Fast and accurate test result Extremely broad testing range, covering low and high permeability High repeatability of testing results Easy set-up of test parameters and sample data The preparation of a sample for the L80-5000 is accomplished in minutes. No grease or glue is required for a tight seal around the sample in the chamber. The test sample is affixed to the self-adhesive sample card, which is inserted into the L80-5000 test chamber, separating the upper and lower chamber. The Lyssy L80-5000 is able to measure high permeability materials using special sample reduction cards that decrease the surface area of the sample. The L80-5000 is the latest generation of the proven L80 series, which has been used successfully for decades in many labs. With the L80-5000, the testing of water vapour permeability becomes very simple. The L80-5000 is easy to operate, and its reliable testing principle and low degree of maintenance have demonstrated to users worldwide the superiority of the Lyssy testing method. The L80-5000 is easy to set up and operate through the built-in alphanumeric keyboard and digital display. With a built in printer the L80-5000 also enables easy test documentation. Complete traceability in test documentation, data logging and error reports Automatic equilibrium detection Automatic temperature control Easy to use test sample holders - no grease needed for sealing Built-in printer Low degree of maintenance This reduction of the surface prevents the system from getting saturated, and therefore it becomes possible to dry down the upper chamber of the instrument and obtain a permeability measurement.
