Pirani Vacuum Gauge

For more information on ULVAC products, purchase, and/or consideration, click here.
Pirani vacuum gauge is a vacuum gauge that utilizes transport phenomenon (thermal conduction) of gases.
Inside the vacuum gauge, a filament built into the electrical circuit is heated. When gas molecules collide with the filament, they remove heat from the filament. Convert that temperature change to pressure.
