RAPID TEMPERATURE CHANGE TEST CHAMBER

Origin: China

Brand: TOPECT

Category: Stability Chamber Tags: Medical, Pharmaceutical

This is a temperature and humidity test chamber specifically engineered to simulate rapid thermal transitions at rates of 5 °C/min, 10 °C/min, or 15 °C/min. It enables high-precision evaluation of the durability and performance of materials, components, and finished products under extreme temperature and humidity fluctuations.
