Main technical parameters
temperature range10 ℃~+70 ℃ (no light conditions)Remarks:< br/> 1. All under empty container conditions (except as indicated), tested according to GB/T5170
2. The test data of the air-cooled test chamber system was tested under good ventilation conditions at room temperature of 25 ℃; When 35 ℃ ≥ room temperature>25 ℃, it can be used normally, but the low temperature range, cooling rate, and thermal load capacity will be affected to some extent< br/> 3. Test data of water-cooled test chamber under the conditions of water temperature ≤ 28 ℃, water pressure between 0.2MPa and 0.6MPa, and inlet and outlet water pressure difference ≥ 0.2MPa
                Temperature fluctuation≤± 0.5 ℃ (no light conditions)
Temperature uniformity≤ 2 ℃ (no light conditions)
Temperature deviation± 2 ℃ (no light conditions)
Humidity range40% to 98% RH (under no light conditions) (see humidity range chart)
Humidity deviation+2~-3%(>75%RH),
± 5% (≤ 75% RH) (under no light conditions)
Heating time≤ 60 minutes (room temperature~+70 ℃)
Light intensity(700-1120) ± 10% W/m2 (adjustable)
Light exposure time1   Adjustable from 0 to 99 hours and 99 minutes
During the irradiation period, the temperature inside the test chamber should rise at a rate close to linear and remain at the set temperature control value (typical settings are+55 ℃ and 40 ℃). During the shutdown phase, the temperature inside the test chamber should decrease at a rate close to linear to the set temperature control value (typical setting value is+25 ℃) and maintain temperature stability. The relationship between temperature, irradiation, and time during different experimental procedures is shown in Figure 2.
Spectral energy distribution and tolerance: should meet the requirements in Table 1
Test timeCan be set within 0-999 hours, Can automatically conduct experiments according to the following test procedures:
Test Procedure A: With a 24-hour cycle, irradiation for 8 hours and 16 hours off, the test period can be set
Test Procedure B: The test cycle is set to 24 hours, with 20 hours of irradiation and 4 hours of shutdown. The test cycle can be adjusted.
Test Procedure C: Continuous irradiation, test time can be set.
Lamp coolingAir cooling (under normal usage conditions, the effective service life of metal halide lamp tubes is 800-1000 hours)
wind speedThe wind speed of the test chamber can be adjusted within the range of 0.5-1.5m/s through a frequency converter;
Attached with the equipment manual is a comparison table of wind speed and frequency converter.
Spectral energy distribution and tolerance: should meet the requirements in Table 1
