4 - Poster Test Chamber

4 - Poster Test Chamber is a large-scale professional testing equipment that combines a multi-channel tire-coupled road simulation system (four-post test rig) with a high- and low-temperature environmental climate chamber. It is used to simulate road spectrum vibration during vehicle driving under controlled extreme temperature and humidity conditions.

Product Details

Model	CZ-AHA-331D-WSOS (Customizable)
Test chamber internal dimensions (W×D×H) (mm)	7200×9200×5000
Door dimensions (W×H) (mm)	3500(1750+1750)×3000
Temperature Range	-40℃ ~ +80℃
Heating / Cooling Rate	-40°C ~ +80°C, ≤120 min, average ≥1.0°C/min (With load, static no heat load)
Humidity Range	10% ~ 95% R.H (Within the temperature range of 20°C ~ 60°C)
Solar Simulation	600–1200 W/m² (Wavelength 280–3000 nm), stepless adjustment, irradiance area: 6000×2500mm
Fresh Air System	Minimum dew point temperature: -40°C, minimum airflow ≥400 m³/h; At an ambient temperature of 20°C, minimum airflow ≥1000 m³/h
Air Velocity	Under the premise of ensuring the temperature uniformity performance of the environmental chamber, the internal air velocity should be kept as low as possible, ensuring an average air velocity of ≤0.8 m/s at the vehicle position on the four-post system.
