Polymer products usually damage when exposed to various environmental conditions which are formed from the atmosphere and earth’s surface. This directly affects the actual life of the product. Hence, it is necessary to test the quality of the polymers to calculate their real life when placed years outside. This can be done proficiently with the help of a testing instrument known as UV Light Accelerated Weathering Tester. The device is widely used to create each and every type of climatic conditions and to study the weather resistant properties of the material inside the laboratory. It has become a very effective method to measure the effect of environmental conditions on the products. Two models of Ultraviolet accelerated weathering testers are available namely,
PSPL 855 ：It is a Basic Ultraviolet Light Accelerated Weathering Cabinet that does not provide irradiance control.
PSPL 856 ：It is an Ultraviolet Light Accelerated Weathering Cabinet that offers Irradiance control along with the facility of automatic calibration.
Optional Accessories: UVB lamps (40w/313nm) / UVA lamps (40W/340nm)
Both PSPL 855 & 856 model are equipped with fluorescent UV lamp to provide the light source inside the chamber. The humidity and the temperature of the instrument can be controlled easily to achieve the periodic condensation on the test specimen to evaluate the damaging factor completely which are caused due to the moisture, sunlight, temperature and various material ageing phenomenon that includes intensity reduction, fading, cracking, flaking, cracking, oxidation and chalking. The Fluorescent UV light creates the effect of sunlight whereas the water spray and condensation creates the impact of dew and rain.
At the time of the test, temperature and radiation energy can be controlled easily. The difficult test cycle usually carries out under the strong ultraviolet radiations and in wet and dark condensation period having relative humidity 100 percent. These types of tests are generally performed in the field of automotive industry, paint, and plating industry, automotive industry, plastic, glue, wood industry, etc.
