UV-B 290~313nm Wavelength UV Aging Test Chamber Industrial With Stainless Steel Plate


This product uses fluorescent ultraviolet lamps that best simulate the UV spectrum in sunlight, and combines temperature control, humidity supply and other devices to simulate sunlight that causes discoloration, brightness, strength decline, cracking, peeling, pulverization, oxidation, etc. damage to materials (UV Section) high temperature, high humidity, condensation, dark rain cycle and other factors, at the same time, through the synergy between ultraviolet light and moisture, the single light resistance or single humidity resistance of the material is weakened or invalidated, so it is widely used for weather resistance of materials performance evaluation.

 

Features:

(1).The installation thickness is adjustable;Easy installation.

(2).Upward spinning door is not in the way of users to operate machine;The machine is only took very small space.

(3).By using special cooling system,the ordinary tap water is allowed to be used.

(4).Very convenient software program;Will automatically alarm if operate wrongly or machine breakdown;light intensity can be programmed.

(5).The lifetime of tube can be extended if has radiation calibrator.(more than 1600 hours)

(6).Can be divided into ordinary type,light irradiation controlling type,spraying type.

 

Standards:

ASTM G 153, ASTM G 154, ASTM D 4329, ASTM D 4799, ASTM D 4587, SAE, J2020, ISO 4892 All current UV aging test standards.

 

Light source:

The light source uses 8 imported UV fluorescent lamps with a rated power of 40W as the light source. Ultraviolet fluorescent tubes are distributed on both sides of the machine, 4 on each side. There are UVA-340 and UVB-313 light sources for users to choose from. The luminescence spectrum energy of the UVA-340 lamp is mainly concentrated at the wavelength of 340 nm, and the luminescence spectrum of the UVB-313 lamp is mainly concentrated near the wavelength of 313 nm. We use the UVA-340 lamp because the fluorescent light energy output will gradually decay with time. In order to reduce the impact of the test due to the attenuation of light energy, this test box is every 1/1 of all eight lamps. When the fluorescent lamp of 4 is used, an old lamp is replaced by a new lamp, so that the ultraviolet light source is always composed of a new lamp and an old lamp, thereby obtaining a constant output light energy. The effective life of the lamp can be around 1600 hours.

 

Power control:

1.Blackboard temperature and condensing temperature are controlled by controller.


2.The rest basically use imported electronic components.

Uniformity of irradiance: ≤ 4% (at the surface of the sample)

Blackboard temperature monitoring: The standard Pt-100 blackboard temperature sensor is used to precisely control the sample surface temperature during the test.

Blackboard temperature setting range: BPT 40-75 °C; but the actual maximum temperature limit of the internal temperature protection device is 93 °C ± 10%.

Blackboard temperature control accuracy: ±0.5 °C


3.Sink temperature monitoring: During the loop test, one test section is a dark condensation process, which requires a saturated water vapor that can generate a higher temperature in the tank. When the water vapor encounters a relatively cold surface of the sample, Dew will condense on the surface of the sample.

The sink is located in the lower part of the cabinet and has an electric heater.

Sink temperature control range: 40~60°C


4.The test box is equipped with a time controller, the range is 0~530H, power failure memory function.


5.Safety protection device:

Over temperature protection inside the box: When the temperature inside the box exceeds 93 °C ± 10%, the machine will automatically cut off the power supply of the lamp and heater, and enter the equilibrium state to cool.

The low water level alarm in the sink prevents the heater from being burned.
