Perspirometer
The Perspirometer is used to determine colour fastness to perspiration, cold water and sea water. The same instrument is employed to predict the potential of white or pastelcoloured textiles to yellow in transit or storage. After insertion of the specimens, the Perspirometer is transferred to an Incubator for a pre-determined period. Following incubation, the Perspirometer is removed and specimens are graded using grey scales.
