Overview of Bench UV Light Accelerated Weathering Test Chamber

The CB-25700 Bench UV Light Accelerated Aging Chamber is an economic and easy-to-use instrument. It is equipped with three 20W UV lamps (313 or 340nm) as light sources. An operator can set total illumination time, temperature and spray time to simulate the natural environment which would reproduce the damage factor from the environment to the samples.
This chamber can isolate 18 piece standard panels (Size is 150×70mm). Samples are installed in a column form,  on the rotating sample rack. During the test, the sample rack rotates uniformly ensuring every sample gets the same irradiance energy in order to optimize comparability and repeatability of testing results.


  • Touch screen and user-friendly operation interface allow the user to set the test parameters and monitor all the test process easily.
  • Equipped with professional UV lamps which have high irradiance energy: 0.90W/m2(On a new lamp).
  • Full stainless steel inner design with sandwich.
  • Its design prevents water vapor from infiltrating into the electrical section and damaging electronic components.
  • Built-in water level switch, will alarm and stop automatically when under low water level.
