1、 Technical parameters of aging test chamber
1. Temperature range: RT+10 ℃~200 ℃, RT+10 ℃~250 ℃, RT+10 ℃~300 ℃
2. Temperature fluctuation: ± 0.5 ℃
3. Temperature uniformity: ± 2.0 ℃
4. Resolution: ± 0.1 ℃
5. Air exchange rate: 1-100 times/h
6. Test timing range: 0.999.9
7. Ventilation time: 0.99.9 (s, m, h)
8. Adjustable ventilation mode: Instrument controlled automatic ventilation.
9. Circulation mode: Fan forced circulation mode.

2、 Material for making the box body of the natural ventilation aging test chamber:
1. Both the inner and outer chambers of the test chamber are made of SUS304 stainless steel plates, and the outer shell is treated with A3 plate spray coating, making it more aesthetically pleasing.
2. The circulating fan adopts a specially designed air conditioning type long shaft, low-noise, long-life motor.
3. The wind turbine is a stainless steel axial flow circulating fan blade.

3、 Heating system
1. Using far-infrared nickel alloy high-speed heating wire
2. High temperature, completely independent ventilation system
3. The temperature control output power is calculated by a microcomputer to achieve high-precision and high-efficiency electricity efficiency

4、 Control system:
1. The instrument adopts LED display microcomputer PID, At self-tuning, SSR output control accuracy: ± 0.1 ℃ Sampling period: 0.2ms Temperature sensor: PT100 platinum resistance thermometer. ]
2. Ventilation control: Ventilation control is instrument automatic control, not natural ventilation. During automatic ventilation, the instrument sets the ventilation frequency, ventilation time, and stop time, and controls the driver to open and close the ventilation valve port.
3. The top of the box is equipped with a ventilation outlet, and the size of the ventilation outlet can be adjusted in advance.
4. The panel control surface is equipped with ventilation operation display and stop display.
5. Safety protection system: The test chamber is equipped with over temperature, timed, overload protection, and fan overheating protection.
