1. Device introduction:
Used to test and verify the conformity of electrical and physical properties of samples in high and low temperature or humid and hot alternating environments; Suitable for industries such as aerospace, electrical and electronic, household appliances, communication, automotive, new energy, military, etc; It can perform high temperature storage, low temperature storage, high temperature and high humidity, alternating humidity and heat. Its linear temperature rise and fall rate of 0.1-5.0/min can be linearly controlled, which is particularly suitable for rapid temperature and humidity combination cycles of automotive components and other climate and environmental tests.
2. Device features :
2.1. This device meets the requirements of the SAE US-CAR standard for the rapid temperature rise and fall rate of temperature and humidity cycling test conditions for automotive electronic samples. The linear heating and cooling rate of the device can achieve linear control of 0.1-5.0; The humidity can simulate and execute high temperature and high humidity environments of "95 ℃&95% RH" and low temperature and low humidity environments of "25 ℃&10% RH".
2.2 Adopting electronic expansion valve servo control of refrigerant flow throttling technology reduces energy consumption by 30%; Continuous operation without fault at low temperature for ≥ 2400 hours; The device has a lifespan over 100000 hours, and its safety performance has passed the EU CE safety certification.
