?Brief Introduction: The tester can provide reliable aging test data to make the exact prediction of products’ weathering fastness(aging resistance)., which is conducive to sift and optimize the formula. It is used in many industries, such as: paint, inks, resin, plastics, printing and packaging, adhesives, auto and motorcycle industry, cosmetics, metal, electronic, electroplating, medicine,etc. ?Characteristics: 1.The ultraviolet aging tester is designed according to uses’ operation , it’s easy to operate, safe and reliable. 2.The thickness of specimen installation is adjustable and the specimen installation is fast and convenient. 3.The door rotating up does not interfere with the operation and the tester takes a very small space only. 4.It’s unique condensating system can be contented by tap water. 5.The heater is under the container rather than in the water, which is long life, easy to maintain. 6.The water level controller is outside the box, easy to monitor. and so on
