UV Test Chamber

UV Test Chamber

1. UV test chamber simulates damaging effects of long term outdoor exposure of materials and coatings by exposing test samples to varying conditions of the most aggressive components of weathering – ultraviolet radiation, moisture and heat.
2. UV test chamber use fluorescent lamps to provide a radiation spectrum centered in the ultraviolet wavelengths. Moisture is provided by forced condensation, and temperature is controlled by heaters. Based on your testing sample’s size, We has two options uv test chambers for choice.

UV Test Chambers

Question 1. Explain what is the relationship between UVA and nm ?
Answer: The wavelength range: 315~400nm, we named it’s UVA light.
Question 2. UVB lamps degrade material quicker than UVA lamps … correct ? Why ?
Answer: The wavelength range: 280~315nm, we named it’s UVB light. Because it’s short wavelength, It maks the testing material with a faster degradation.
Question 3. What is Irradiance ?
Answer: Irradiance is the unit, the lighting/ lamp’s strength. Unit: W/m2
Question 4. Is the test data downloaded to a spreadsheet or other format ?
Answer: Yes, You can use a USB and take it into the USB port of UV test chamber. The test data will transfer to USB automaticlly, You can check the data by computer by Excel formt.
Question 5. Single or Three phase power ?
Answer: We have single phase 230V, 50Hz, and three phase 380V, 50Hz for your options.
Question 6. Does Wewontech also provide color identification test units? For instance I would place my material into the UV test unit and I’d like to measure the change in color (if any) from before test and after test.
Answer: We don’t have the color identification equipment. If you found a good supplier from China, We can buy it for you and shipping to you together with our UV test chamber.
Question 7. How long does it take to simulate a 12 month test? And do you simply double this time frame for a 24 month test? Triple for a 36 month test, etc ?
Answer: It depends on different testing environmental. For examples, In Guangdong, China, The outdoors temperature range: +15– +20C, Testing 1 day in UV test chamber equal to simulate 28-30 days for outdoors test.
Question 8. Can you pause a 36 month test at the 12 and 24 month point to inspect and record information ?
Answer: Normally, The deterioration degree is nonlinearity, It can not doing a simple adding way !
