Carleton Life Support Systems Inc. TTU-520A/E Aircraft Oxygen System (AOS) Test Set

Since pilots have had the need to breathe at high altitudes, Carleton Life Support Systems Inc. has been there for them, providing oxygen enriched air and committing to the safety of their mission.
Carleton Life Support Systems is a world leader in the application of air separation technology for aviation applications and in the design and manufacture of miniature sterling cycle cryogenic coolers. Bendix Aviation founded the company in 1951 and the sold the facility to Litton Industries in 1982.

TTU-520A/E Aircraft Oxygen System (AOS) Test Set

The TTU-520A/E AOS test set is a self-contained portable testing unit with attachments required for functional testing and adjustment of an on board molecular sieve aircraft oxygen system, excluding the oxygen regulator, in the aircraft cockpit at the organizational maintenance level.

The AOS test set is used to measure the oxygen concentration of the product gas from a concentrator at high or low flow rates. It measures the analog output voltage from the aircraft oxygen monitor and converts that value to indicate oxygen partial pressure. It measures and indicates product gas delivery pressure from the concentrator and verifies the proper operation of oxygen monitor warning signal circuit and the continuity of the aircraft oxygen monitor heater circuit (CRU-83/A and CRU-91/A). This test set is used in the testing of oxygen concentrator models OC1009 and OC1077.
