UV weathering test machine moist Simulation[ All QUV ultraviolet weathering tests provide thermal coagulation wet cycles, a harsh and real moist exposure environment. In general, products exposed to outdoor are often in a humid state in humidity for 15 hours. QUV provides two wet simulation methods. Because some application conditions also require water spray to achieve the actual effect, some QUV models can run a condensation cycle and run water spray cycle.
* Water spray The weathering test machine spray type can simulate the effect of rainwater, such as thermal impact and water erosion.Under certain practical applications, such as in the sun, the aggregated heat is rapidly dissipated due to a sudden shower, the temperature of the material will grow sharply, produce thermal shock, this thermal shock is for many The material is a test. The water spray of the QUV can simulate thermal shock and / or stress corrosion.
* Condensation method
The condensing method is the best way to simulate the moisture erosion of outdoor, and the most application. All QUV models can run condensation cycles
In the design of the weather testing machine, the sample actually constitutes the side wall of the test chamber, the back surface of the sample is exposed to the laboratory indoor air. The cooling effect of indoor air results in a low surface temperature than the water vapor temperature, thereby ensuring that the water vapor continuously condenses the surface of the sample. This condensate is a very stable pure distilled water.In the condensation cycle, water vapor is generated by heating the bottom water tray of the test. Hot water steam allows the test chamber to maintain 100% relative humidity at higher temperatures.

QUV UV weathering test machine UVA-340 lamp can provide optimum sunlight simulation Spectral, critical short wavelength range from 365 nm to sunlight cutoff wavelength 295 nm.
UVA-351 lampQUV UV weathering test machine UVA-351 / imageEs / img / 6.jpg lamp can simulate the sun through the window glass Light ultraviolet portion. Thisthe most material testing interior application, which is used to reproduce some of the degree of damage to some inks and polymers in the environment near the window.
UVB-313 lampThe UVB-313 lamp tube of the QUV UV-Tester is mostly utilized than usually the ultraviolet rays that usually appear on the surface of the earth. Short-wave ultraviolet. Therefore, for some materials, these tubes may result in unrealistic precise results. The UVB-313 lamp is preferably used for quality control and research and development applications, or materials for testing very durable.
is also referred to as FS-40 or F40UVB, which is the initial QUV lamp. FlyThe S-40 lamp is still used in some traditional automotive test methods. QFS-40 lamps should only be used only for QUV / BASIC UV weathering testing machines.
Cool white lamp
Cool white lamp tube (only for QUV / CW model only) can effectively reproduce and accelerate the simulation office Indoor lighting in the business environment, as well as retail display lighting.
In addition to all models other than QUV / basic type, QUV Solar Eye irradiance sensor needs to be calibrated by the user to ensure accurate, consistent. It is only a few minutes to clear the human error.
The irradiance calibration CR10 is used with UVA-340, UVA-351 or UVB-313 lamp tubes, and the CR10 / CW irradiation is only used with the cold white tubeThe CR10 and CR10 / CW irradiation meter need to return to QS-lab once a year to recalibration, and there is very little cost. Our calibration laboratory has passed the American Laboratory Certification Association and the ISO 17025 certification of England Certificate.
