Thermal vacuum chamber testing of our ICI-5 Sounding Rocket Mission magnetometer and student balloon project. We use the thermovac to simulate the extreme conditions of space and see how our instruments perform.

Small Vacuum Test Chamber


  • High Vacuum (<10-6 Torr) 

  • Dry scroll pump for oil-free rough pumping 

  • Turbopump to achieve high vacuum 

  • Nitrogen backfill with options for higher purity gases 

Test Volume: 

  • Test volume of 23 x 17 x 15” 

  • Aluminum plate with standard hole pattern to mount UUT 

  • Optional CQCM  

  • Note: This may reduce allowable UUT height  

Temperature Control: 

  • Thermal platen 

  • -100 to 260C 

  • Chamber walls 

  • +35 to 220C 

  • 11 available thermocouples 


  • Various CF/KF feedthrough options available 


  • Chamber door inside ISO7 softwall cleantent with ESD flooring 

  • Feedthroughs all outside the cleantent to allow operator to monitor UUT in a normal lab environment 


  • Optional CQCM for real-time contamination measurements
