- The pressure gauge is retrieved from a yellow machine in a side room of the upper chambers of the ATLAS substructure during the quest Mother of Invention. The variant of the pressure gauge that is acquired depends on the option chosen when interacting with the machine. Strength 4+ is required to get the pressure gauge in good condition, by removing the screws and fighting through the rust.
- A non-quest version of the pressure gauge can be retrieved from Arktos Pharma biome lab, on the ground next to the deposit machine in habitat A.
All of the quest items retrieved during the latter half of Mother of Invention, during the "Extract components from the ATLAS machines" objective and including the pressure gauge, are removed from the player character's inventory upon speaking with Scribe Valdez at the conclusion of the quest.
