Ageing chamber UVTest

UVTest is an aging chamber with 8 fluorescent UV lamps (UVA 340, UVB 313, UVA 351). The device is designed to test resistance to photo-oxidation, i.e. to ultraviolet (UV) radiation in its most destructive range – UVA and UVB.
 
 
The UVTest chamber allows control of the test parameters: the intensity of the UV radiation and the temperature the samples are exposed to during the test. Programming and monitoring of tests takes place through a built-in microprocessor controller with an LCD touch screen. High repeatability of tests is ensured by the ultraviolet (UV) calibration system.
 
  • Range of radiation intensity adjustment: from 0.35 to 1.55 W/m2 for UV-A lamps and from 0.35 to 1.23 W/m2 for UV-B lamps,
  • Black plate temperature control range (BPT): 35-80 ° C for the light phase, 35-60 ° C for the condensation/coating phase.
