The Filtratest serves for inspection of the purity and exact determination of impurity concentrations in textile polymers (e.g. PET, PA) and other thermoplastic melts.

The melt flows through a fine-meshed filter blank, wherein impurities tip little by little.Caused by the deposited dirt particles the pressure increases and is measured by means of transducers and recorded during measurement.

The subsequent analysis of the sieves allows evidence to form and quantity of the impurities.
