Advanced Environmental Chamber for Temperature , Humidity , & Altitude Control
Altitude Test Chambers seamlessly combine temperature and altitude settings, with the added option of humidity control, allowing for simultaneous environmental testing. Users can easily adjust the chamber temperature while subjecting the product under test to varying altitude levels, reaching up to 100mBar. This innovative blend of features enables precise simulation of real-life conditions, providing invaluable insights into how products perform at different altitude levels.
