It is used to determine the colour fastness of textiles to perspiration and to assess a garment's potential to yellow when conducting phenolic yellowing testing. The device consists of a stainless steel frame, which takes a number of acrylic or glass separator plates. A load is applied and the Perspirometer is placed inside an Incubator. The equipment complies with the ISO 105 series and AATCC 15. We supply Incubators and required accessories and test materials.
