Altitude Chambers

Simulating altitude/vacuum and temperature for combined environmental testing

CSZ Altitude Chambers combine temperature and altitude with optional humidity to test basic components or sub-assemblies for a variety of industries. Standard altitude chambers simulate altitude up to 100,000 feet (8.2 Torr) and higher levels optional up to 175,000 feet (.37 Torr). Optional extended ranges are also available to simulate sea level testing when your site is significantly above sea level.

These chambers meet many test standards for altitude testing including IEC and Mil-Stds.

  • IEC 60068-2-13
  • MIL-STD-202
  • MIL-STD-810
  • MIL-STD-883
  • Other commercial test requirements

Touch Screen Controller
  • CSZ EZT-570 Touch Screen Controller is designed to save chamber programming and setup time. Standard features data logging, data file access via memory stick or PC, Ethernet control and monitoring, alarm notification via email or phone text message, full system security, online help & voice assistance in multiple languages and more.
  • A Temperature Limit and alarm is included to protect your product.
  • Safety relay connection is provided to protect your device under test by removing power to it when the chamber is not running.
EZ-View Software
  • RS-232/485 serial communications, Ethernet control and monitoring offer a selection of communications options.
  • EZ-View optional software allows user to control and monitor up to 20 chambers from any location.
Altitude Test Chamber
  • 3" (8 cm) ports for ease of cable routing – larger sizes available.
  • Fully welded ports and shelf pilasters eliminate potential leaks, increasing the life of your chamber.
  • All liners are constructed from Type 304 brushed stainless steel that is easy to clean. All seams are continuously welded to form a hermetically sealed unit to prevent moisture migration.
  • The chamber exterior is constructed of formed sheet steel for structural strength and finished with a textured polyurethane paint. Customer specified paint combinations are available upon request.
  • Robust Vacuum System - Heavy duty, high capacity vacuum pumps provide reliable performance. System is equipped for controlling altitude setpoints automatically with a regulating rate of ascent and descent by using manual adjustable valves. Flexible section in vacuum lines also prevents transmission of adverse vibration.
Altitude Chamber Refrigeration
  • Pressure gauges allow operating pressures to be continuously monitored and provide early warning indicators.
  • CSZ test chambers utilize refrigerants which are environmentally safe, non-flammable, non-explosive and have a Zero Ozone Depletion Potential (ODP).
Altitude Humidity Chamber
  • An electronic humidity sensor is used on all humidity models for accuracy and minimal maintenance.
  • Humidity water filtration system to filter impurities and protect chamber interior
