Overview of the Optimization Tester

The QUV photocodynation tester can reproduce the destruction of several months or years to produce a few months: including Fading, discoloration, powdering, cracking, brightness decrease, variation, embrittlement, strength decrease, and oxidation. Reliable aging test data can accurately correlate the weather resistance (anti-aging) nature of the product, and help the screening and optimization of materials and formulations. It has become a global use of the most widely used aging test chamber in the world, there have been thousands of QUV photocondensing testers .

Optical Tester Function

UV light and sunlight simulation

According to different test conditions There are several different ultraviolet lamps to choose from. QUV

The fluorescence ultraviolet lamp of the photocondoscopic tester

can simulate the most important short-wave ultraviolet light in the sunshine, the aging of material physical properties caused by the illuminating light. Wet Simulation

The models of all photocondosition testers provide thermal condensation moist 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. The photocodynate tester provides two moisture simulation methods. Because some application conditions also require water spray to achieve the actual effect, some of the photocodynation tester models can operate both condensation cycles and run water spray cycles.

* Condensation method

The condensing method is the best way to simulate outdoor moisture erosion and the most application. All of the photocondens testers can operate in condensation cycles

In many outdoor environments, the moisture time of the material can be as long as 12 hours. Studies have shown that this main factor in this outdoor damp is dew, not rain. The photocondural tester simulates outdoor moisture erosion by a unique condensation function. In the condensation cycle, water vapor is generated by heating the test chamber bottom water tray. Hot water steam allows the test chamber to maintain 100% relative humidity at higher temperatures.

In the design of the photocondary tester, the sample actually constitutes the sidewall of the test chamber, and 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.

* Water spray

Photoelectric tester spray type can simulate the effect of rainwater, such as thermal impact and water erosion.

Under certain actual applications, such as in the sun, the amount of material is rapidly dissipated due to a sudden shower, and the temperature of the material will have a sharp change, generate thermal shock, this thermal shockMany materials are a test. QUV water spray can simulate thermal shock and / or stress corrosion

Optical Tester Model


Photoelectric Tester

QUV / S is the most common QUV model, using QUV / SE this simple test equipment, you can achieve ideal accelerated aging test at a lower price

* Equipped with solar eye radial illuminance control system that can accurately monitor UV irradiance.

* Has a condensation function to simulate outdoor moisture erosion. * Provides fast, reproducible test, longer tube life and calibration according to ISO metrological standard requirements. QUV / Spray

Photoelectric Tester

QUV / Spray with standard QUV / SE

Photo aging tester

basically, in spray Derived water is recommended when cycling.

* Equipped with a water spray system, including nozzles, pipelines, control and drainage devices.

* Short-time spray can simulate thermal shock, long spray can be used to simulate mechanical erosion caused by rainwater.

* Ultraviolet light, spray or condensation function can be realized.

QUV / CW Photo aging tester

Many industries require cool white light to perform indoor product light resistance test, QUV / CW Photo aging test The instrument can reproduce this indoor lighting environment.

* Compliant with indoor light resistance test standards such as ISO, ANSI and ASTM.

* Equipped with sun eye radial illuminance control system to monitor the light intensity of the cold fluorescent lamp.

* Use a cold white fluorescent lamp to simulate an indoor lighting environment, such as a fluorescent lamp commonly used in the office.


Optimization Tester

It is recommended that only QUV / BASIC is selected when making comparison exposure tests, that is, at the same time, the test samples in the same trial machine And refer to the sample to expose the comparative experiment

* QUV's basic model, suitable for laboratory with limited budget.

* Control the irradiance by regularly replacing the lamp and the rotation lamp position. QUV / BASIC has a condensation function analog moisture, but does not have water spray function. * The high-radiation illuminance test cannot be performed because it is not equipped with the sun eye radial illuminance control system, and there is no automatic adjustment or calibration.

The most commonly used photocondural tester model is QUV / Spray, QUV / SE. Understand more parameter information Welcome consultation: 400 6808 138
