Benchtop Ultraviolet（UV） Light Accelerated Weathering Tester

Description:

This instrument is suitable for speed up weathering test through light, water exposed to predict the relative durability of paint, coating, plastic, such non metal, especially suitable to view the physical performance breakdown of special durable material such as gloss reduction, fog image, deterioration of strength , powdering cracking, bubbling, embrittlement and fading, etc.

Same as other fast test in lab, you can’t apply the test result of this unit to replace the natural expose to judge the actual year of durability of the material, but the contrast test condition provided by this unit is relative practical for fast assessing the weathering resistance of material, screening or improve the new & old formula, monitoring the quality of products.

As the ultraviolet light is the main lighting factor to cause the deterioration of durability for outdoor products plus the relative stable distribution of light spectrum energy and low price so this LUV testers become the most widespread kind of weathering test in the world by it’s advantage of fast ,convenient and economy. As a simple model this unit special suitable to the laboratory with limit economies.

The revolution of rotating frame design adopted by this unit can compensate the uneven defect of light radiate caused by the factor of light tube aging and difference of batches, so to save the heavy work of regular exchanging the sample position according to the sequence required  by normal tester.

Because the water is the important breakdown factor for fast aging, so this unit adopts the water spray mode to imitate the influence of moisture. To set the spray time you can compare the environment condition which approached some final application, such as the mechanical corrosion caused by severe temp. change or raining flush. To meet the application requirement of strong and durable of weathering tester, this unit adopts the corrosion-proof stainless steel for construction parts to make simple construction design for the convenience of application and maintenance. So just pay the relative low cost you can find out in a short time the material damage formed under the natural condition for long time, to judge the difference of quality between the tested products and samples.

Features：

◆ Touch screen and user-friendly operation interface allow handlers set the test parameters and monitor all the test process easily.
◆ Equipped with professional UV lamps who has high irradiance energy: 0.90W/m2（New lamp） 
◆ Full stainless steel inner working room with sandwich design, never getting rusty and leakage. Also prevent water vapour coming from working room from entering electrical box and damaging electron components.

◆ Biult-in water level switch, it will alarm and stop running automatically when under low water level.
