Test Principle

The ultraviolet rays of sunlight are the main factor who damage weathering resistance of most materials. We use UV lamps to simulate the short wave part of sunlight, it produce few visible lights and infrared lights. According to different testing requirements, we choose different wavelength UV lamps, this is because each type UV lamps produce different irradiance energy and wavelength. Generally speaking, UV lamps can be divided into UVA and UVB.

Different types fluorescent UV lamps are used in different fields, for example:

① UVA-340 Lamp: UVA-340 Lamp can highly simulate short-wave ultraviolet light of sunlight, the wavelength range is from 365 nm to 295 nm.

② UVA 351 Lamp: Simulates UV sunlight which has passed through the windows. It is excellent for testing materials aging process indoor.

③ UVB-313 Lamp: UVB-313 lamp emits stronger shortwave ultraviolet light compared with the ultraviolet rays on Earth, thus can accelerate material aging process. However, this lamp may cause some unrealistic material damage. It is mainly used in quality control, research and development, and the test of the materials with strong weather resistance.

BGD 852 Bench UV light Accelerated Aging Chambers is an economic and easy-to-use  machine which can meet some customers’ requirements. It is equipped with 3 pcs 20W UVA or UVB lamps as light sources. Operator can set the total illumination time, temperature, spray time etc to simulate the natural environment which would cause the damaged factor to samples.

This chamber can isolate 18 pcs standard panels （Size is 150×70mm）. Samples are installed a column form rotating sample rack. During the test, the sample rack rotate uniformly and ensure every sample get the same irradiance energy, increase the compariability and repeatability of testing results.

Features：

◆ Touch screen and user-friendly operation interface allow handlers set the test parameters and monitor all the test process easily.

◆ Equipped with professional UV lamps who has high irradiance energy 0.70W/m²（New UVA lamp）

◆ Full stainless steel inner working room with sandwich design, never getting rusty and leakage. Also prevent water vapour coming from working room from entering electrical box and damaging electron components.

◆ Biult-in water level switch, it will alarm and stop running automatically when under low water level.
