Sharing: Common Components of UV Aging Test Chambers

Source：LINPIN Time：2025-04-09 Category：Industry News

A UV aging test chamber is composed of many components, each playing an indispensable role. Today, we will introduce some of the common components.

1. Fluorescent Lamps
Fluorescent lamps are a crucial component of UV aging test chambers because the equipment uses them as the light source. Common types of fluorescent lamps include UV-A, UV-B, and UV-C, which are differentiated by their ultraviolet wavelengths:

UV-A: Wavelength of 320–400 nm (used for light curing).
UV-B: Wavelength of 290–320 nm (medium wavelength).
UV-C: Wavelength of 200–280 nm (used for disinfection and sterilization).
The test chamber typically uses UV-B lamps, with two rows installed inside, each containing four lamps. The energy output of fluorescent lamps decreases over time. To minimize the impact of energy reduction on tests, when one-quarter of the lamp’s lifespan has elapsed, one old lamp in each row should be replaced with a new one. Regular replacement ensures stable energy output.

2. Black Panel Thermometer
This instrument consists of a 7.5 cm × 1 cm × 0.25 cm black aluminum plate connected to a temperature sensor. Its primary function is to measure the test temperature.

3. Sample Holder
Used to place test specimens, this component includes a cushioning plate, frame base, and tension springs. The frame base and cushioning plate are made of aluminum alloy.

4. Radiometer
Depending on test requirements, a radiometer is used to measure radiation levels. Common types include cumulative illuminance meters and radiometers.

The above introduces some key components of UV aging test chambers. Understanding these details helps optimize the use of the equipment. UV aging test chambers are widely used in environmental testing for products such as mobile phone accessories, automotive parts, and electronics. They are also applicable in specialized fields like military and aerospace.
