Bench UV Light Accelerated Weathering Tester (Touch Screen)

Polymers are widely used in different industries, from commercial to domestic, it has never ending applications. With time, the quality of polymer starts to degrade due to various factors. Environmental conditions, play a major role in deteriorating the basic properties of the polymers. While estimating the shelf life of the product, it is necessary to test the product in accelerated intended working conditions. To test the endurance and durability of the product, weathering conditions are simulated depending upon the intended real working conditions. This helps in assessing the behaviour of the product and estimate the life. Presto’s Bench UV Light Accelerated Weathering Tester (Touch Screen) allows to test the product in different weathering conditions.

Polymer responds differently in different weathering conditions. This machine simulates conditions like rain, humidity, temperature, UV light, condensation. It’s a very efficient technique to analyse the product in one chamber for different conditions. The conditions are simulated in a cyclic manner. However, every condition is emulated in a controlled manner. It allows the operator to check the response like cracking, colour fading abrasion, flaking etc. very easily. Irradiance and temperature can be controlled very easily. Since it is an accelerated test, the conditions inside the chamber are very extreme. It is a very fast and economic way of testing and analysing the products. It is used widely in different industries to test polymer, paint, metal, textile and rubber. Presto’s 5-in-1 machine is boon for different industries. As it not only saves the cost but helps a lot in cutting down the testing time. It’s a compact models can be fit anywhere in the laboratory. To make the machine works in the best way, it is always advised to install in ideal lab conditions.

Features of Bench UV Light Accelerated Weathering Tester (Touch Screen)
