On October 24, 2014, Dr. Alan Eustace used a state-of-the-art Pressure Suit Assembly to ascend to the top of the stratosphere beneath a large, helium-filled plastic balloon and sky dive back to Earth. He reached a maximum altitude of 135,889 feet before parachuting back to Earth, breaking the previous world record. He accomplished this mission by using a pressure suit alone for life support and foregoing the weight of a balloon gondola to ascend to the stratosphere.

This altimeter was used by Eustace during his jump. Larsen and Brusgaard, manufacturers of skydiving altimeters, built this Quattro model. It accurately measures freefall and canopy descent rates. It was placed in Eustace's helmet and provided automated altimeter warnings.

The Eustace-Kwan family donated the altimeters as part of the suit donation to the museum in 2015.
