Commercial pressure gauge for 0-30 psi systems

This commercial pressure gauge measures from 0 to 30 psi with a 2 inch dial and 1/4 inch NPT male bottom connection. It suits technicians monitoring low-pressure air, water or oil lines in HVAC, hydraulic or pneumatic installations. The +/-3-2-3 percent accuracy class meets typical commercial test requirements. The 304 stainless steel case and acrylic lens resist corrosion in workshop environments.

Liquid-filled vibration resistance

The gauge is liquid-filled to dampen needle flutter caused by pump pulsation or mechanical vibration, giving a steadier reading than dry models. No field-fill option is provided, so the factory fill is permanent. The acrylic lens and white dial maintain visibility under shop lighting. California Proposition 65 warnings apply because the product contains listed chemicals.

+/-3-2-3 percent accuracy class

The +/-3-2-3 percent accuracy specification determines whether this gauge meets your test protocol or quality standard. Buyers needing tighter tolerance or a certified calibration certificate should verify suitability before purchase. The gauge is not rated for IP or NEMA sealing, so it is not suited for wash-down or outdoor exposure. It lacks a field-fill port, so users who prefer to refresh fill fluid cannot do so.

Questions about this item

Will the 304 stainless steel case need any special maintenance to prevent corrosion?

The 304 stainless steel case resists corrosion under normal conditions; wipe it clean with a damp cloth and avoid prolonged exposure to harsh chemicals.

What is the accuracy limit of the gauge when monitoring pressure continuously up to 30 psi?

Accuracy is rated at +/-3-2-3 percent of span, meaning the middle third of the scale reads within +/-2 percent.

Does the acrylic lens or dry movement cause noticeable heat buildup or noise during all-day operation?

The gauge has no powered parts, so it generates no heat or noise; the acrylic lens and dry movement remain passive during use.
