This 80 liters weather ometer has a same testing performance, Compare with the USA famous brand, such as ATLAS, Q-LAB, the similar model.
The matching and assembly for this 80 liters weather ometer is perfect. The main functional components are imported parts with international quality level. The body structure has an improved safety and reliability performance. This can make the 80 liters weather ometer guarantee a long-term for using, without any quality claims happen.

80 liters weather ometer

The 80 liters weather ometer equip with a xenon arc lamp, It is a simulation and accelerated weathering accelerated aging test equipment, The test results of near atmospheric aging were quickly obtained to evaluate the weatherability of the material.

Weathering test is an important method for selecting the optimal composition of the screening formula in scientific research production process. It is also an important part of quality inspection. Application materials such as paints, plastics, aluminum-plastic panels, and automotive safety glass products which require the weatherability test.


Xenon Lamp Powerxenon Long-arc Lamp, 2.5KW X(1PC)
Xenon Lamp Wavelength
250-800nm, To maximize the reproduction of the aging mechanism of sunlight,
It can be set that the sample to be tested is continuously exposed to the lighting environment equivalent to noon in the summer for 24 hours.
Compared with the actual outdoor environment, the average light intensity is stronger and the average daily exposure time is longer, so that the test results can be quickly obtained.
Radiation Intensity
35-70 W/M2 (at 300-400nm) Adjustable
0.30-0.57 W/M2 (at 340nm) Adjustable
300-800 W/M2 (at 200-800nm) Adjustable
0.66-1.22 W/M2 (at 420nm) Adjustable
650-1200 W/M2 (at 200-3000nm) Adjustable

There has 5 model radiation testing options in weather ometer control system. They are UVA 340, UVA 420, 200~800nm, 300~400nm, 200~3000nm. The customer has a choice there when they are doing a radiation test. Meanwhile, If your engineer plan to do a custom xenon aging test, Please inquiry to us timely. Because we need make sure this weather ometer can meet your testing requirement.

We use our Irradiance tester to check the inner radiation intensity, According to our testing record, We noticed that our 80 liters weather ometer has a better irradiance control and intensity range performance, Compare with the China radiation testing standard requirement. The below is the real testing data and recorded by our engineer during the test, Let me share with you. Hope you like it.


Radiation Type (W/m2/nm)Radioactivity


Can we set and maintain an irradiance in the range of 0.35 W/m2 and at either of the wavelength 313 or 340 or 353 nm ?
When you use 340 nm wavelength, You can set and maintain 0.30W~ 0.57W/m2. So 0.35W/m2 for 340nm wavelength is no problem for sure !
Is it also possible to set a particular wavelength out of above three to get 0.35W/m2 irradiance ? If Yes then either of the three or any one ?
Here are the wavelength and irradiance for Wewon weather ometer which we can guarantee !
0.30~0.57 W/m2 (at 340nm)0.60~1.22W/m2 (at 420nm)35~68W/m2 (at 300~400nm)350~580W/m2 (at 300~800nm)
I noticed that Wewon xenon weather ometer irradiance range can be 150~ 1500 W/m2, Does it below the UL 2256 spec which request for 0.35 W/m2 ? If 150W/m2 is the minimum level how its possible to set at a level of 0.35W/m2 ?
150~ 1500 W/m2 (at 250nm ~ 3000nm) /When the customer use a 150 W/m2, It can not meet the 0.35W/m2 level.
In fact, The 0.35W/m2 irradiance will be worked with some of the test condition, Like 340nm wavelength. It is not comply with all the wavelengths test.
