UV Light Accelerated Weathering Tester

PSPL 855

The UV Light Accelerated Weathering Tester is a highly efficient and easy to use a testing instrument that can be used for accurate analysis of the effect of the weathering factors on a material or product. The Factors like moisture, sunlight, temperature, etc. can cause degradation of the polymers such as fading, cracking, flaking, etc. In order to ensure long life and better performance of the products, it is important to test the effects of the factors on a particular product or material. The instrument is provided with a fluorescent UV light that can exactly emulate the effects of the sunshine, while the water spray and condensation function can easily replicate the rain and dew factors. The temperature and irradiance can be controlled easily. The testing procedure is generally conducted under strong irradiance of ultraviolet light with up to 100% humidity. The instrument is easy to operate and provides an economical way of testing the materials and products. It is an ideal testing instrument for textiles, paints, rubber and plastic industries.

Most of the raw materials that are used in various industries experience the degradation of quality due to the natural environmental conditions and elements like Ultraviolet, moistures, sunlight, etc. This has great effect on the durability and performance of the polymers. It is important to test the effects of these factors on the polymeric products to make sure that they would be able to survive through the rough environmental conditions and factors. The UV Light Accelerated Weathering Tester offered by Presto is one of the best testing instruments that can provide stable and repeatable testing results for the effects of weathering on a product.

    I run the business of polymers and after reviewing the features of this tester in testing instruments, I decided to buy this product. First of all I wish to thanks the manufacturer of the UV light accelerated weathering tester as they saved me from unavoidable circumstances and helped me in growing my business. Testing the effect of different natural environmental conditions on polymers can be tested earlier that helps in improving the quality of the material.
