Large Walk-In Rapid Temperature Change Humidity Test Chamber

Zhongzhi Testing Instruments' large walk-in rapid temperature change and humidity test room is suitable for safety performance testing of aerospace products, information electronic instruments, materials, electrical engineering, electronic products and electronic components, product screening tests, etc. At the same time, this test can improve product reliability and product quality control. The cold system reduces vibration and noise, and controls the temperature by adjusting the refrigerant flow to control the refrigeration energy. There is no need to heat to balance the refrigeration. The technical performance is 20% to 45% higher than that of traditional hot and cold dynamic balancing technology, and PID is adaptive, and the control is continuously corrected according to the temperature conditions to achieve the control purpose of fast convergence, small temperature overshoot, and high stability.
