Capsule Vacuum Gauges
AIRTECH’s Capsule Vacuum Gauges are designed to measure absolute pressure in Torr and give readings that are independent of barometric pressure. Variation of pressure causes deformation of the hermetically-sealed aneroid capsule. The evacuated capsule transfers this movement mechanically to the pointer that indicates the pressure in absolute terms.

Bourdon Tube Vacuum Gauges
The AIRTECH Bourdon Tube Vacuum Gauges are designed for general vacuum service. These gauges are commonly used on central systems, in OEM applications and for industrial services that require indication in inches of mercury (in. Hg).
This general purpose gauge is designed for use when pressure medium is non-corrosive to brass or phosphor bronze.
