Commercial Compound Gauge 30 to 0 to 30 psi

This commercial compound gauge measures vacuum and pressure across a 30 to 0 to 30 psi range. It features a 2 1/2 in dial with white face and +/-3-2-3 percent accuracy. The case uses 304 stainless steel with an acrylic lens. A 1/4 in male NPT connection mounts at the bottom. The unit is liquid-filled for vibration resistance and is not field fillable.

Technicians monitoring vacuum

Suits technicians who need a single gauge showing both vacuum and positive pressure on the same dial. The liquid-filled design handles vibration in industrial or automotive settings. Buyers requiring a field-fillable gauge or an IP-rated enclosure should look elsewhere. This model also lacks a dry dampening feature for applications preferring non-liquid filling.

Range headroom for combined vacuum

The 30 to 0 to 30 psi span comfortably covers typical manifold testing and HVAC evacuation checks where both sides of zero are read. Accuracy holds to +/-3-2-3 percent across the scale. Headroom ends at the 30 psi limit; systems running higher positive pressures or deeper vacuum need a gauge with a wider range.

Questions about this item

What fitting do I need on my system to connect the 1/4 in NPT male process connection?

The gauge has a 1/4 in NPT male thread at the bottom; you need a matching 1/4 in NPT female port or adapter on your equipment.

Will the +/-3-2-3 percent accuracy hold when I use this gauge next to older analogue gauges on the same line?

Yes, the 304 stainless steel case and acrylic lens are rated to the same pressure range of 30 to 0 to 30 psi, so it reads consistently alongside legacy instruments.

How can I confirm the gauge is reading correctly after I install it?

Apply a known vacuum and pressure within the 30 to 0 to 30 psi span and verify the needle moves smoothly across the white dial to the expected marks.
