Programmable Temperature.Humidity.Vacuum Test Chambers

High altitude low pressure (Vacuum) simulation test chamber

Altitude test chamber

Grande can provide custom-built chambers for simultaneous testing of temperature and low-pressure altitude conditions. Two common applications are:

· Testing of avionics or other aerospace equipment to simulate actual conditions it might experience.

· Simulation of high-altitude conditions like might be found in mountainous regions.

NOTE: Altitude test chambers are custom systems, and differing requirements may significantly change the cost and utility requirements. Please let Grande know as much detail as possible about your anticipated testing specification/method, and we can provide you with a tailored system for your requirements.
