Latest company news about UV Weather Resistant Test Chamber

Equipment For Simulating Climate Conditions


The test chamber uses a fluorescent ultraviolet lamp as the light source, and by simulating the ultraviolet radiation and condensation in natural sunlight, the accelerated weather resistance test of the material is carried out to obtain the weather resistance result of the material. It can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, darkness and other environmental conditions in natural climates, and by reproducing these conditions, combine them into a cycle, and let it automatically execute the number of cycles


It is suitable for performance reliability test of various industrial products, designed and manufactured with reference to GB/T14522-93, GB/T16585-1996 and GB/T16422.3-1997 and other corresponding standard clauses;


The UV accelerated weather test chamber reproduces the damage caused by sunlight, rain and dew. The device conducts the test by exposing the material to be tested to a controlled alternating cycle of sunlight and moisture while raising the temperature. The device uses UV fluorescent lamps to simulate sunlight, and can also simulate the effects of moisture through condensation or spray. It is a necessary test equipment in the fields of aviation, automobile, home appliances, scientific research, etc. It is suitable for schools, factories, military industries, research institutes, and other units.


Characteristics of UV light weather resistance test chamber


The body of the UV light weather resistance test box is processed and formed by CNC machine tools, and the shape is beautiful and generous. The box cover is a two-way flip type, which is easy to operate.

The inner liner of the box is made of imported high-grade stainless steel, and the outer liner of the box is sprayed with A3 steel plate, which increases the appearance texture and cleanliness of the ultraviolet light aging test box.

The heating method is the inner tank water tank heating, the temperature rises quickly, and the temperature distribution is uniform. The drainage system uses the vortex type and U-shaped sedimentation device for drainage, which is convenient for users to clean.

The ultraviolet light weather resistance test box uses a black aluminum plate to connect the temperature sensor, and the black plate temperature instrument is used to control the heating, and the temperature is more stable.


The radiometer probe is fixed and does not need to be loaded and unloaded every time.
The amount of radiation is displayed and measured by a dedicated UV radiation meter with high precision.

The radiance of the UV weather resistance test chamber is not more than 50W/m.

Lighting and condensation can be controlled independently and can be controlled alternately.
The independent control time of light and condensation and the time of alternating cycle control can be set arbitrarily within one thousand hours.

Temperature control of UV weather resistance test chamber



During the UV light cycle period in the UV light weather resistance test chamber, the photochemical reaction is usually not sensitive to temperature. But the rate of any subsequent reaction is dependent on the temperature. The rate of these reactions increases with increasing temperature. Therefore, it is very important to control the temperature during UV exposure. In addition, the temperature of the accelerated weathering test must be consistent with the maximum temperature at which the material is directly exposed to sunlight.


In the UV light weather resistance test chamber, the UV exposure temperature can be set at any temperature between 50°C and 75°C according to the illuminance and ambient temperature. The UV exposure temperature is regulated by a sensitive thermostat and blower system so that the temperature of the test chamber has excellent uniformity.


Precautions and maintenance of UV weather resistance test chamber


1. During the operation of the equipment, be sure to maintain a sufficient water source.

2. In the test phase, the time for opening the door should be minimized.
3. There is a sensing device in the working room, and do not suffer strong impact.

4. If you need to use it again after a long time, you must carefully check the water source, power supply and various components, and then start the device after confirming that it is correct.

5. Because ultraviolet radiation has a strong hazard to personnel (especially eyes), operators should minimize exposure to ultraviolet rays (contact time should be less than 1min). It is recommended that operators wear protective goggles and protective covers.

6. When the equipment is not working, it should be kept dry, the water after running should be drained, and the working room and box should be wiped dry.

7. After use, cover the plastic cover to avoid dust intrusion. If there is dust, it should be removed.
