1、 Product introduction

This series of equipment simulates the harm of sunlight and dew on materials and products, and is widely used to evaluate the weather resistance of materials.

The imported intelligent temperature and humidity controller is used for temperature control and humidity control, with PID adjustment and rapid self-tuning, and various parameters can be set. The temperature and humidity are directly displayed by digital, and the reading is very convenient. The inner tank material is made of high-grade stainless steel, which is beautiful and elegant in overall appearance.

Main technical parameters
temperature range 10 ℃~ + 70 ℃ (no light condition) remarks:
1. All of them are tested according to GB / t5170 under the condition of empty container (unless otherwise specified)
2. The air-cooled test chamber is tested at room temperature of 25 ℃ and well ventilated. When 35 ℃ ≥ room temperature > 25 ℃, it can be used normally, but the low temperature range, cooling rate and thermal load capacity will be affected.
3. The test data of water-cooled test chamber were measured under the conditions of water temperature ≤ 28 ℃, water pressure of 0.2mpa-0.6mpa, and inlet and outlet water pressure difference ≥ 0.2MPa
Temperature fluctuation 5 ℃ (no light condition)
Temperature uniformity ≤ 2 ℃ (no light condition)
Temperature deviation ± 2 ℃ (no light condition)
Humidity range 40% ~ 98% RH (no light condition) (see humidity range chart)
Humidity deviation +2~-3%(>75%RH),
± 5% (≤ 75% RH) (no light condition)
Heating time ≤ 60min (room temperature ~ + 70 ℃)
Light intensity (700 ~ 1120) ± 10% w / m2 (adjustable)
Illumination time 1.0 ~ 99h99min adjustable
2. During the irradiation period, the temperature in the test chamber shall rise to and maintain at the set temperature control value (typical setting values are + 55 ℃ and 40 ℃). In the stop lighting stage, the temperature in the test chamber should be reduced to the set temperature control value (the typical setting value is + 25 ℃) at a nearly linear rate, and the temperature should be stable. Under different test procedures, the relationship between temperature, irradiation and time during the test is shown in Fig. 2.
3 spectral energy distribution and tolerance: should meet the requirements of Table 1
Test time zero It can be set within ~ 999h, and the test can be carried out automatically according to the following test procedures:
Test procedure a: 24 hours as a cycle cycle, 8 hours of irradiation, 16 hours of stopping exposure, the test cycle can be set
Test procedure B: take 24 hours as a cycle, irradiate for 20 hours, stop exposure for 4 hours, the test cycle can be set.
Test procedure C: continuous irradiation, test time can be set.
Lamp cooling Air cooling (under normal conditions, the effective service life of metal halide lamp tube is 800-1000 hours)
wind speed The wind speed of the test chamber can be adjusted in the range of 0.5 ~ 1.5 m / s through the frequency converter;
The comparison table of wind speed and frequency converter is attached with the equipment manual.
Spectral energy distribution and tolerance: should meet the requirements of Table 1 (Fig. 3)
Spectral region Ultraviolet B Ultraviolet A visible light infrared
Bandwidth μ M 0.28~0.32 0.32~0.40 0.40~0.52 0.52~0.64 0.64~0.78 0.78~3.00
Radiation intensity w / m2 five sixty-three two hundred one hundred and eighty-six one hundred and seventy-four four hundred and ninety-two
Tolerance% ±35 ±25 ±10 ±10 ±10 ±20
