Method of
work:

During the measuring the testing samples are put into the measuring instrument whereby an optical contact is achieved. Secondary fluorescent light falls on photocell. Photocell is located in front of the filter for absorption of the primary UV radiation. Photocell converts the amount of light into an electrical signal that is manifested through increased hands to remove the demonstration instrument.

Department,
room, location:

Department for Textile Chemistry and Ecology, Textile Research Laboratory, Savska cesta 16/9
