UV Test Chambers

UV aging test chamber have been developed to provide a UV weathering. The UV simulates the effect of sunlight with fluorescent ultraviolet (UV) lamps, while rain and dew are simulated by the condensation of humidity. As stated previously, the UV light only represents roughly 5% of the sunlight but it is responsible for most of the polymer degradation. Also, materials are often tested with equipment, which simulate only the shortest wavelengths (UV). The UV-B range includes the shortest wavelengths found in sunlight. Therefore, for many applications, it is a fast and efficient method.
UV aging test chamber uses two main types of lamps: UVA-340 and UVB-313. While these lamps have different light emission spectrum, they are both characterized by a maximum of emission in the UV range. UVA provides a reasonable match of the UV region of the solar spectrum, but this match is no longer valid for the long wavelengths (visible, IR).

UV Test Chambers

UVB lamps also emit UV light, but the maximum of the emission spectrum is shifted towards short wavelengths compared to the UVA lamps. The UVB-313 lamp is a widely used type of fluorescent UV lamp that provides fast test results. However, the spectrum contains short wavelengths, which are not present in the solar radiation.
● Feature: Stainless steel SUS#304 made, easy setting operation. Ventilation measurement function.
● Wing diffusion supply air circulation system, fresh air ventilation can be arbitrary adjustment.
● Internal rotary free dismantling, Suspension frame motors speed is 8-10 rpm.
● Optional accessories( Temp. Recorder, calibrated rack for 9 points calibration)
● Best after sales service: One year free parts maintenance. Meet international test standards.
Introduction & Application: UV test chambers simulates the environment of high temperature atmospheric pressure environment, which is used to heat resistance test for electrical insulation, ventilation aging test of electronic parts, plasticizing product, leather textile test, treatment of mandatory ventilation, etc.

We can choose the UV light wavelengths depending on different test requirements, since every UV radiation and wavelength of the light is not same. Usually, UV lamps can be divided into UVA and UVB. More details check and custom requirement, Please inquiry us by mail.

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 !
