Engineered with liquid-filled design for superior stability and accuracy, this gauge minimizes needle vibration in demanding environments. The dual-scale reading (-30inHG to 30PSI) accommodates both vacuum and pressure applications, making it remarkably versatile for tube systems, water pumps, gas lines, and precision liquid pressure testing. A helpful range mark pointer guides you to optimal operating zones for quick visual reference. The robust stainless steel construction resists corrosion, i for café beverage systems and kitchen equipment exposed to moisture and humidity.
