UV Light Accelerated Aging Test Chamber,Anti Ultraviolet Test Machine, UV Accelerated Weathering Tester Its technical parameters fully comply with the national standard GB/T1865-2009; ISO11341:2004 "Paints and Varnishes - Artificial Climate Aging and Artificial Radiation Exposure", ISO4892 "Plastics - Laboratory Light Source Exposure Methods", ASTM D3451 "Testing of Paint Powders and Powder Coatings", and ASTM D3794 "Testing of Coil Coatings". This instrument uses an LCD liquid crystal display, which is intuitive and easy to operate, replacing the cumbersome operation of the (old) LUV-II instrument; The adoption of high-precision digital temperature sensors and the use of PID regulation greatly improve the accuracy of temperature control; In addition, a time memory function has been added to avoid a sudden power outage during the test process, resulting in a restart of the test.
