Key Features & Advantages

Glycerin Filled Anti-Vibration Stability

The glycerin liquid dampens internal movement, preventing pointer flutter under pulsating vacuum conditions.

Compact 50mm Industrial Design

Small diameter design makes it suitable for tight installation spaces and OEM equipment integration.

Stainless Steel Corrosion Resistant Housing

SS304 case ensures long-term durability in humid, industrial and outdoor environments.

Vacuum Measurement Capability

Accurate measurement from 0 to 250 psi makes it ideal for vacuum pump and negative pressure systems.

EN 837-1 Standard Manufacturing

Built according to international pressure gauge standards ensuring interchangeability and reliability.

Working Principle

The bourdon tube deforms under vacuum pressure and transfers motion to the pointer mechanism, which displays real-time pressure values.
