The L80 series of analyzers have been used successfully for decades in many laboratories. The L80-6000 is the latest generation of the proven L80 series, used around the world. Simple to use with a reliable testing principle and low maintenance this instrument is a cost effective solution. The Lyssy L80-6000 can measure high permeability materials using special sample cards. It is extremely quick and the more permeable the sample the shorter the measuring time. In addition to its short testing times and wide measurement range, it offers a high degree of accuracy.
The accuracy and wide measuring range of 0.03 - 10,000 g/m2/day are achieved by using a highly sensitive and reliable humidity sensor which is located directly in the measuring chamber. This test method offers the best reproduction of real-life conditions, since no carrier gas or extractive measuring technique is used.
The humidity sensor is very stable, regardless of the humidity range in which it is operated. As a result, the L80-6000 alternates quickly and easily between low and high permeability measurements. Typically, the change can be done in one hour or less using the 'Simulated Test standard' function.
