UV Aging Test Chamber

Light Source

1. The light source employs eight imported ultraviolet fluorescent lamps, each rated at 40W. These ultraviolet fluorescent tubes are distributed across both sides of the machine, with four tubes on each side. Users may select either UVA-340 or UVB-313 light sources for configuration;

2. The spectral energy of UVA-340 tubes is primarily concentrated at 340nm wavelength, while UVB-313 tubes concentrate around 313nm;

3. This apparatus employs UVA-340 tubes;

4. As fluorescent lamp energy output gradually diminishes over time, to minimise the impact of light energy decay on testing, this chamber replaces one old lamp with a new one every quarter of the total lamp lifespan across all eight lamps. This ensures the ultraviolet light source is always composed of both new and old lamps, thereby maintaining a constant light energy output;

5.  Effective lamp lifespan is approximately 1600 hours;

6.  Equipped with a true-colour touchscreen PID temperature intelligent controller, offering high precision and excellent stability;

Electrical Control

1.  Black panel temperature and condensation temperature are both controlled via the controller;

2.  Primarily utilises imported electronic components; irradiance uniformity: ≤4% (at the sample surface);

3. Black plate temperature monitoring: Utilises standard Pt-100 black plate temperature sensors to precisely regulate sample surface temperature throughout testing;

4. Black plate temperature setting range: BPT 40-75°C;

5. Temperature protection device threshold: Maximum limit of 93°C ±10%;

6. Black plate temperature control accuracy: ±0.5°C;

7. Water Tank Temperature Monitoring: During the cyclic test, a test phase involves dark condensation where the chamber must generate saturated water vapour at elevated temperatures. When this vapour encounters the relatively cooler specimen surface, condensation forms dew droplets;

8. Water Tank Positioned at Chamber Base with Built-in Electric Heater;

9. Water Tank Temperature Control Range: 40–60°C;

10. The test chamber is equipped with a time controller, range 0–530 hours, with power failure memory function;

Standard Specimen Clamps

1. Supplied with several standard specimen clamps (75×150 mm or 75×290 mm, thickness 1–15 mm);

2.  Non-standard dimensions must be specified by the user at the time of ordering;

3.  Samples may be loaded directly without the use of sample holders or racks;

4.  Standard sample holders feature 14 rows per surface, with one rear row designated for mounting a blackboard thermometer;

Chamber Construction Materials

1.  Inner chamber constructed entirely from SUS304 stainless steel plate;

2.  Outer casing manufactured from SUS304 stainless steel plate;

3.  Sample racks feature stainless steel and aluminium alloy mesh frames for convenient sample access;

Structural Description

1.  The chamber is manufactured using CNC equipment, featuring advanced craftsmanship, sleek lines, and an aesthetically pleasing design;

2.  The chamber material is 1.0mm thick SUS304 stainless steel;

3.  The internal air duct employs a single-cycle system with one imported axial fan, enhancing airflow velocity and heating capacity while significantly improving temperature uniformity within the test chamber;

4.  Water supply and consumption: approximately 8 litres per day of tap or distilled water;

5.  Heating method employs an internal water tank system, delivering rapid temperature rise and uniform thermal distribution;

6.  Door features a single-direction pull mechanism for effortless, smooth closure;

7.  Automatic water replenishment for the internal tank prevents dry-firing damage to heating elements;

8. Specimen racks constructed from stainless steel or aluminium alloy;

9. Unit base fitted with high-quality PU castors for mobility;                  

10. Drainage system utilises U-shaped sediment trap;

11. Specimen surfaces maintained parallel to UV lamp plane;

12. Internal spray system incorporates automatic nozzles with adjustable water pressure;
