  1. 1.0 1.1 The mass and drag are from the part config, but the game handles it massless/dragless.

The PresMat Barometer measures the current atmospheric pressure. In career mode, it is available with Survivability, at level 3 of the technology tree. As of 0.24.2 , it had "PhysicsSignificance = 1", making it a zero drag and physicsless part.


It shows pressure in kPa units. A pressure below 0.0001 atm is shown as vacuum by the sensor. Lower atmospheric pressures markedly reduce lift and drag induced by the atmosphere, and cause a small change in engine efficiency.

While it is activated, the barometer drains 0.0075 units of Electric Charge per second (0.45 ⚡/m, 27 ⚡/hr).

While in previous versions the PressMat could not be used to earn science in a vacuum, in 1.0 this was changed. The PresMat can now do science nearly anywhere.
