> Model no. H3003-0018 Dynamic difference calorimeter for determining the oxidation induction time for polymer pipe and protective pipe systems as well as moulded elements made of polyolefins. The length of time the anti-oxidant remains in the test sample and thus prevents oxidation is measured. The test sample is kept at a constant, predetermined temperature in flowing oxygen during this test. The dynamic difference calorimeter provides a large meas­ur­ing range at high resolution. This quality device is characterised by high temperature accuracy and reproducibility as well as high manufacturing quality and the latest sensor technology.
