1. Device introduction:
The equipment is used to test and verify the conformity of electrical and physical properties of samples under high and low temperature or alternating humidity and heat environments,so it widely used in aviation, aerospace, electronics, electrical appliances, communications, automobiles, new energy, military and other industries; It can perform high temperature storage, low temperature storage, high temperature and humidity, humidity and heat alternating change test.
2. Device features :
2.1. The device can perform tests for "85 ℃&85% RH" high temperature and high humidity, "40 ℃&10% RH" high temperature and low humidity, "25 ℃&5% RH" low temperature and low humidity; And ensure that no condensation or water droplets are generated during the testing process. Simultaneously, it can achieve precise control of both temperature and humidity slopes by synchronously implementing the linear slope rise and fall of humidity under the condition of "temperature linear rise or fall";
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.
